Is this tank overstocked?

[nanoreefer15]

Tank: IM Nuvo Fusion 20

 

Livestock:

1 ocellaris clownfish

1 royal gramma

1 tail spot blenny

1 firefish

1 clown goby

 

Assortment of inverts (cleaner shrimp, hermits, snails, starfish/urchin, clams, fan worm)

 

Thanks!

Depends on your water quality, I would say the starfish and urchin were probably a bad idea based upon their behavior and what they eat, urchins will bulldoze, and the starfish will prob starve if there is not enough food for it to eat. Gramma can be very aggressive and protective on their area they carve out a good amount of space for themselves. Do you have any little caves for him/her?

Is this the stocking you plan on or already have? I would say it's a little heavy. The bigger shrimp (Skunk Cleaners/Blood/Banded Corals) are considered as another fish because they get to decent sizes. I'm not sure about the urchin.

 

If anything you should choose between the Royal Gramma or Tail Spot since they have the same habits (living in the rocks).

 

Personally I would go with the Clown, Tail spot, Firefish, and the goby.

 

Hope that helps a little!

Here is a pretty cool idea, since you're still in a small tank, have you thought about getting maybe 3 or 5 sexy shrimp, they are cool and fun to watch and stay pretty small.

I want to add a lot of dry, porous rock (maybe reef cleaners?) so would that be good for the gramma, or would he still be aggressive towards the others like the tail spot?

I haven't set it up yet lol, just making sure. I really love the purple and yellow and the cuteness of grammas but yeah, maybe that would be a problem with the blenny. I also like how funny and cute blennies are .

 

I was thinking of getting a 30l instead but that seems a little to expensive right now for me to be able to stock all that space with corals. But I love the footprint of tank.

 

For the shrimp I might just get one skunk cleaner shrimp or one sexy shrimp like omelette said.

 

Still torn between my fish stock though

What are you going to be doing to maintain water quality?

[nanoreefer15]

What are you going to be doing to maintain water quality?

I'll do 25% water changes a week. I won't run a skimmer or reactor until much later on. I'll start with one fish and then add another fish every month or so.

[charnelhouse]

Whether or not you intend to keep SPS corals also comes into play. If you aren't keeping SPS you can afford to sacrifice a little water quality to more fish. Skimmer/no skimmer is another factor.

 

If you intend on getting a skimmer, get it from the start. Get used to monitoring and maintaining it. And save yourself the headache of trying to play catch-up to your bioload down the line.

It's a little overstocked in my opinion. I'd lose one of the fish. If you do plan on having this as a stock list I would plan on doing a lot of water changes and skimming heavily

To be honest, with that bio-load I would do smaller water changes every other day if not every day. I would also add the gramma last.

What about if I removed the clown goby so I have:

 

1 ocellaris clownfish

1 tail spot blenny

1 firefish

1 royal gramma

 

Would that still be overstocked/need heavy skimming and a lot of heavy water changes?

The Clown Goby is tiny and likely wont make a big difference. I'd lose the Firefish or Gramma

Hard decision because I love both! Which one do you suggest in your opinion?

[dpoltsdsu]

I'd keep the Gramma. They are a bit less skiddish than Firefish and are way less likely to jump out of the tank. They also provide some Yellow in the tank thats difficult to find in nano reef tanks

[12_egg_Omelette]

The gramma is the most aggressive fish

There. Add him last if you add him at all

If you're really thinking on overstocking, you need to maintain very good water quality. Usually thrice weekly WCs would be good (around 25% to 40%) and if you have a skimmer or very large fuge stocked with macro to provide nutrient export, then you should do decent. However, you have to be careful with your fish list. The way I see it - you have 2 perchers:

 

Clown Goby

TSB

 

and two fish that requires caves/shady areas/boltholes:

 

Firefish

Royal Gramma

 

The clownfish would technically be an open swimmer, so it doesn't matter. But you have to adjust your scaping to accommodate everyone if you're following through with 5 fish. Yes, it is overstocked. But if you want to play safe, I say axe out the Gramma and go for the firefish. Grammas can be a bit territorial if you don't give them enough room and a good cave. But firefish has its cons - they're very skittish and tend to jump more than the average fish. Also, that clown you're getting needs to either be a Percula or Occy because other clown species will grow too big and require larger room to swim.

 

As for the TSB, I have one and I notice how much he loves to shelter in the giant pores of my LR. So if you have particularly porous LR or a cluster of old barnacles or seashells, that'd be a good shelter for the blenny. Clown Gobies on the other hand will perch on anything including coral, but they might snack on SPS polyps (mainly Acros) so be careful if you're planning on introducing SPS to your tank later on.

Thanks for the advice! If I were to only get

1 ocellaris clownfish

1 royal gramma

1 tailspot blenny or firefish (not sure which yet)

 

Would that be fine and not need as many water changes?

 

If I add a clown goby to that list because they're small, would that have a large impact/require more water changes? I'd rather do 1 25%-35% water change per week, maybe 2 max, so I need to adjust my stocking accordingly.

[piano15]

Are you planning in keeping corals? Clown goby are know coral nippers.

 

Blennies are awesome!

Firefish are jumpers so you may want to use some mesh to cover the top.

I think sticking with 3 fish is the best. Or if you insist on doing 4, axe out the Royal Gramma completely. Clown gobies generally have very low bioloads, so it won't put a large dent on your WC. Clownfish on the other hand will since they're little SW piglets and generate an enormous amount of waste daily.

 

If you're going with that amount of WC, you really need either a good skimmer or refugium for nutrient export. Otherwise, you have to up your WCs. Believe me, I tried overstocking before in a 16G tank. I once had 6 fish in it - despite having an in-tank fuge packed with macro and doing 2x WCs per week, I still couldn't keep up with the water quality.

[dpoltsdsu]

The Gramma, Clown, and Blenny would be fine in my opinion with adequate filtration.

[nanoreefer15]

Thanks for all the replies everyone! So this is what I'm thinking:

 

1 ocellaris clownfish

1 tail spot blenny

1 royal gramma

(Added to the tank in that order)

 

Inverts:

1 skunk cleaner shrimp

1 scarlet hermit crab

1 nessarius snail

1 trochus snail

1 cerith snail

 

Maybe some of those pretty clams or sea fans later. Also lots of coral definitely.

 

How's it look? Thanks!
