I. Introduction

 

The purpose of this thread is to provide you with a fairly comprehensive guide to fish for the nano reef aquarium.

 

As reefing in general is not an exact science the approach I have taken to organizing this information is to provide a framework that includes my knowledge and experience with nano fish both as a hobbyist and professionally, but also to encourage others to share their experience and knowledge for the benefit of everyone.

 

Your Responsibility As A Fish Owner

 

• Fish are living things and deserve to be cared for as you would any other animal. Their life and well-being should not be valued by their price or just because they are easy to replace. As a fish owner you should strive to give your fish the most natural life possible, respecting that you have removed this animal from it's natural environment. To be straightforward, if you aren't willing to put forth the effort, time, money, and do the necessary research to properly take care of and create the ideal environment for your fish, you need to find a different hobby.
  

Words Of Wisdom

• Design your aquarium around what fish you would like to inhabit it with. Never expect a fish to just adapt to a less than adequate tank size.
  
• Plan your aquarium around the maximumsize the fish will get. Just because it is a baby does not give you an excuse to keep it in a smaller tank.
  
• Regardless of what the fish guy at Walmart told you, fish do not only grow to the size of the tank you put them in.
  
• Fish stores are businesses and looking to make money. There are some great fish stores that really do care about their customers, their customer's tanks, and give out great advice. Unfortunately, that is not as often the case as it should be. Exercise extreme caution when taking advice from fish stores until you know they are really interested in helping you have an amazing tank and not just taking your money.
  
• Research, research, and more research! Learn everything you can!
  

 

II. How To Use This Guide

 

Basic Overview

 

There are four major sections with in this guide: feeding, compatibility (coming soon), fish suggestions by tank size, and fish suggestions by group. The feeding section allows you to get feeding suggestions based on diet type (carnivore, herbivore, omnivore, etc.) and more specifically by fish group, which includes more detailed info.

 

The compatibility section will most likely be in the form of a table in which you will be able to see how the species interacts with other fish species, corals, and invertebrates. In the fish by tank size section a list of appropriate fish will follow each of the major divisions of tank sizes, as well, include a brief estimation of how many fish would appropriate for that tank size. In the fish by group section, more detailed information will be provided about the major group each fish belongs to with some specific notes about each fish when necessary. You will also see a estimated maximum size the fish will grow to and the ideal tank size. The ideal tank size will be a compromise based on what is socially practiced by many nano-reefers and what is often recommended by experts. Some of these ideal tank sizes may be controversial and if you believe so, you are welcome to bring that up in this thread so we can all as a community discuss it.

 

Things To Keep In Mind

 

• -Some of this will surely be my opinion or the opinion of others. If you feel strongly against something I have said, please pm me so we can discuss it and make changes if necessary.
  -This is just to get you started--ultimately you need to do more research on your fish choice before buying
  -Also keep in mind I may list some things that are pushing it. I don’t know whether you are a beginner or expert, if you know how to do a water change or not, so I will assume anyone who uses this guide has some common sense and basic understanding of nano reefing. For example, the fact that I list some fish appropriate for a 0.5g and 2.5g tank, does not automatically mean you should keep a fish in a tank that size. Rather, it means if you are capable of maintaining the added bioload of keeping a fish in a tank that size, then these fish would be appropriate choices.
  -Don’t forget to keep your bioload in mind. While a dwarf lionfish may only get 4-6”, due to their diet, the contribution to your tanks bioload will be much more significant.
  

 

How You Can Contribute To This Thread

 

Again, I would like to strongly encourage everyone to share his or her knowledge and experience. Please feel free to suggest additions, corrections, or other changes.

 

Also, I've tried to make note when a species is available captive-bred, so if you learn of a new species that is available, let me know!

 

III. General Feeding Info

 

General Thoughts

 

Meeting the nutritional needs of your fish is absolutely essential to their growth, survival, and reproduction. When feeding fish, we are trying to replicate not only what a fish eats, but when and how it eats in nature. The feeding preference of fish typically falls into one of five categories: carnivores, who eat meaty foods; herbivores, who eat plant matter; omnivores, who eat both meat and plants; piscivores, who eat other fish; and finally lamnivores (detrivores), who obtain their energy from eating the animal and plant matter found with in detritus. You can get a good idea of what to feed your fish just by figuring out what feeding category your fish falls into. It's important to remember that not only can you starve your fish, but you can actually overfeed them too, both of which can have negative health consequences. Fish are opportunistic eaters, meaning they never know when they will get their next meal, so eat whenever food is a available. You many notice your fish eats anytime you put food in the aquarium, but that doesn't mean they are hungry, rather just taking advantage of an opportunity. While it is important for you to feed your fish, you also need to limit feeding too. Overfeeding usually has drastic consequences on water quality anyways, so why would you want to put food in your tank if you don't have to. There are few different types of food commonly available: live, flake/pellet/freeze-dried, frozen, and some hobbyists feed fresh meats and/or vegetable/algae. For the purpose of keeping things simple I am mostly going to stick with what the average reefer is feeding, which is usually a commercially prepared flake/pellet and/or commercially frozen foods. I am revisit this topic later at some point to include live and fresh foods, but wont really get into that right now.

 

A few things to keep in mind

• -The more variety the better...keep multiple types of food and switch things up frequently. Feed a general staple food such as plain frozen brine shrimp or a general omnivore flake food (such as ocean nutrition formula one) and then supplement that with a variety of other frozen, flake, fresh, and live foods.
  -Stick with high quality foods that are low in moisture, ash, and high in vitamins and nutrients.
  -Use or mix in foods that are enhanced with HUFA, omega-3 fatty acids, and vitamin C. Liquid supplements are also available that can be added to any type of food.
  -Do not overfeed!
  -Again, I will provide you with suggestions, but ultimately it is up to you to research the nutritional requirements of your fish.
  

 

Note: In making my suggestions I will refer to foods specifically made by Ocean Nutrition, H2O Life, and San Fransisco Bay Brand, given these are the brands I use and have the most experience with. There are many other high quality manufactures of fish food though and those manufactures often have comparable products that you could use in place of the brands I mention if you wish.

 

Feeding Schedule

 

There really isn't an great well-summarizing answer to how often or how much you should feed your fish with a lot of what you hear being based on experience and/or opinion. Some people feed once a day, some feed every other day, and others feed small amounts several times a day. I don't think one way is right over the other, but for simplicity, will suggest a small amount once or twice a day. You want to try to incorporate in as much variety as you can. If you feed once a day, feed something different or switch back and forth every day. If you feed twice a day, perhaps try frozen at the first feeding and flake at the second. Again, with feeding twice a day I'd suggest your second feeding complement what you did with your first feeding. For example, if in the morning you fed a meaty high protein frozen food then use an algae/seaweed flake for the second feeding. The amount you feed...although I'm not a fan of rules of thumb, I think only feeding what your fish can fully eat in about 5 minutes is a good place to start. If it is all gone before 5 min, perhaps add a little more. If there is a lot of extra food flying around after 5 min, obviously you need to cut back. Any extra uneaten food will have a negative impact on your water quality. Have a good sharp knife too because most likely you will be using fractions of frozen cubes, not the whole cube. For that reason, it can be easier to use frozen flat packs which make it easier to break off only what you need, if the frozen food type you want is available that way.

 

How to use the feeding suggestion guide

 

There are two different ways you can use the feeding guide. I will provide feeding suggestions based on if the fish is a carnivore, herbivore, omnivore, piscivore, or detrivore and I will also provide feeding suggestions for each specific group of fish, noting species that do not follow trends of the group as a whole or have additional special needs. To save time, so I don't have to repeat myself, I'm going to make a list of the common foods by manufacture, and then will refer to those foods by number in both sections of the guide.

VII. Nano Fish Listed By Tank Size

 

Note: Suggestions for Seahorses by tank size can be found under the "Seahorse" heading in the next section of the guide, Nano Fish Listed By Group, for the time being.

 

Key

• Green = Beginner (Ideal for first time fish owners and or new tanks)
  Black = Intermediate (Ideal for hobbyists with established tanks)
  Red = Difficult (Ideal for experience hobbyists who can meet the special needs of these fish)
  ** = Available Tank Raised (Please let me know if I am missing any)
  V = Venomous
  

 

Note: There is a lot of controversy around the idea of keeping saltwater fish in tanks under 10g. Whether or not it is ethical will be up to you to decide and not something I'm going to get into. Like it or not, the fact is there are going to be people who do it. Therefore, I would rather at least provide those people with some guidance to make good choices instead of just leaving them in the dark.

 

Note Mandarins/Dragonets: There is a lot of controversy around the idea of keeping fish from the Dragonet family in nano tanks. Whether or not it is ethical will be for you to decide and not something I'm going to get into. I personally do not encourage people to keep dragonets in nano tanks, however, despite my feelings there a many who have successfully kept them in smaller tanks, there for I will include them in this guide.

Thank you, Amber.

[c est ma]

Wow!

 

Please add green-banded goby. OK in 5 gallon...at least in mine.

 

--Diane

[lgreen]

added

 

good suggestion

 

thanks

[nanoman4]

good guide.

my bicolor blenny is doing great in my minibow 7

[lgreen]

interesting thanks.

 

puffers/tobys and wrasses added.

 

will finish seahorses later.

[Fishfreak218]

WOW! i think this should be a sticky or in the info. section or something....Great Job!!

 

-josh

p.s. i didnt get anything THAT cool for x-mas Lgreen, i willl post pics of what i got on ur other thread

[lgreen]

lol

 

i haven't even bothered going down stairs yet. everyone else is dead asleep.

 

thanks for the compliments

 

read the section on grammas if you get bored lol

 

ps..nothing that cool...your a dork.

 

do i have a bmw sitting in my driveway with a bow on top?

 

lol j/k

[Pili]

OMG! lgreen, you have no life j/k

 

One to add to the anthias section, the fathead (or sunburst) anthias. Its probebly the best nano anthias and can be kept in a 30 gallon +.

[lgreen]

oh yah, caeser777 has one of those in her nano. i will add that.

 

thanks pili

[sandlot13]

great write up....... should be a sticky or something so its easy to find for everyone. Where in idaho do you live lgreen? I go to school in washington, but have lived in idaho most of my life. (Eagle, Boise area) Keep up the good work

[lgreen]

same (eagle, west boise area)

 

where did you go to high school?

 

thanks

[sammydee]

Why bother putting the copyright thing at the bottom?

 

Just out of pure interest, what gain does it give you not to allow others to copy and reproduce your work?

 

sam

[Carinya]

Very nicely done. I appreciate the effort & time this took. In my very humble opinion, your fishload suggestions are a bit on the high side. 3 clowns or damsels in a 10g just seems like too much. I know we can make exceptions for extra small fish like the tiny gobies but I have always heard a good conservative rule is 1 inch of fish for 7 gallons. If you want to push it, do 1 inch per 5 gallons. But that is just me. Skimming, refugiums, sumps (for more water volume) & similar "extras" help us get to the 1 inch of fish per 5 gallons.

 

C

[sammydee]

One inch per five gallons seems very conservative. By that reckoning I could only keep one firefish (3 inches) plus a very tiny goby in my 20L. It depends on frequency of water changes/presence of a skimmer/amount of live rock IMHO.

 

Sam

[Tigahboy]

Putting any kind of fish in a 0.5g might be questionable? I dunno, just seems awfully small to put a fish in.

[lgreen]

do you remember MLA from high school? or citing primary literature for scientific papers?

 

It has nothing to do w/ people being able to use my work. What it does have to do with is others copying my work and claiming it as their own.

 

For example, the list of nano fish based on tank size, is my origional thinking based on my research and opinions. If someone copied that list exactly, that would not be their origional thinking, and therefore they would be stealing. Now, if they use it, and give credit to the person they got it from, then that is cool.

 

There is nothing wrong with using someones info, but you should always give credit to them for that info.

 

For example you will notice throughout this thread I give credit to certain people and books.

 

If you do not not your source, that is plagerism, and basically stealing.

[qualudethunder]

The Rainford Goby does not eat algae, but rather the microorganisms that live within the algae. Think dragonet... along those lines of difficulty.

Totally agree with both of you, but like i said, in some cases i may push the limits. Different people will be at different skill levels and what not, so i would rather provide an answer that covers everyone that just say no period. Although i wouldn't keep fish in a tank under 5g.

 

I'm not a huge fan of inch per gallon rules.

 

for example, 4 inch lion in a 30g is going to be a lot different than a 4 inch goby in a 30g.

 

ok, for general, but you wont catch me using them.

 

The Rainford Goby does not eat algae, but rather the microorganisms that live within the algae. Think dragonet... along those lines of difficulty.

 

I'd be glad to change it. Do you happen to have any literature or anything where I could confirm that? Michael's books seems to suggest it both ways, so i'd be interested to see if algae play a role only as you say, or if they are also able to use the algae directly for nutrition.

[qualudethunder]

I only know from reading peoples personal experiences, mine included but I will try and find some write ups.

[BREAD]

a valentini toby in a 10g? i always that they needed a 30g+ tank or a 20g long at the very least. arn't they puffers also, so they're really messy eaters and produce a large amounts of waste? i dont know, picturing a valentini in a 10g seems pretty sad to me.

[lgreen]

Yah probably, I will change it 20g.

 

Kind of a matter of opinion there. Seems like a single valenti by itself in a true 10g, (not nanocube), could work if you know what you are doing, but yah, perhaps that is pushing it a little farther than I should.

 

keep the comments coming

[sammydee]

"If you do not

your source, that is plagerism, and basically stealing."

 

Totally and utterly WRONG. This is the attitude that is the root of so many of the problems we as consumers have with DRM and other crap like that we get from the RIAA and MPAA.

 

It is not stealing, it is copyright violation, which is totally different. "Protection of intellectual property" has gone completely overboard IMO.

[lgreen]

copyrighting every post is rediculous yes, i dont do that. however, this is something I wrote outside of nano-reef and spent a descent amount of time writing.

 

it is no different than if i started posting sections from michael paletta's books on here and claiming i wrote them.

 

that would be plagerism.

 

should some other idaho reefer be able to copy and paste this into our reef clubs news letter and put their name as the author?

 

if someone takes the article on nano fish I wrote and posts it or publishes it as their own, then it is plagerism.

[Travis]

Hey lgreen, great guide and thanks!

 

Under Wrasses, you have the 4-Line listed as a 10g min., but I have had this fish before and I have to say that a 10g is not enough room at all, 20g min for sure. They like to hunt pods and weeve in and out of tight crevisses of the LR. There's just not enough room for that type of stuff to be happening in a 10g.

[pet_doc]

lgreen: neat thread

 

any specific reason that I couldn't keep a bicolor pseudochromis in a 7? doesn't seem much larger than a clown?

 

TIA
