-E- Posted January 1, 2017 Share Posted January 1, 2017 Currently considering a six line, a royal gramma, or yellow tail damsel (or similar chrysiptera species). I only want one fish plus cuc but every thread I read seems to focus on aggression and community compatibility. I'm more concerned about frequency of feeding (office tank with 2-3 day weekends), and I don't know if I have a sustainable population of pods (no sump, no fuge). Running 4x39w t5 hanging 6" above waterline. This cannot be changed but rockwork has 4 shaded areas. Any thoughts? Link to comment
jedimasterben Posted January 1, 2017 Share Posted January 1, 2017 Pretty much any fish can regularly go several days without food, so I wouldn't really sorry about that. A 20 gallon with a single fish is going to look pretty empty. I would personally for a few different Chrysiptera species (almost all stay very small), or if you're still set on a single one, then get a C. starki. Link to comment
-E- Posted January 2, 2017 Author Share Posted January 2, 2017 ...any fish can regularly go several days without food... That's what I thought but every website says they should be fed 2-4 times per day. Would prefer the look of a solo fish instead of 2-3 fish antagonizing each other. Also not sure if system can handle bioload of multiple fish (even if they're little fish). Link to comment
-E- Posted January 2, 2017 Author Share Posted January 2, 2017 FROGFISH Interestingly hideous but not necessarily reef safe (according to liveaquaria). Link to comment
Pajama_Card Posted January 2, 2017 Share Posted January 2, 2017 Interestingly hideous but not necessarily reef safe (according to liveaquaria). This is because they will perch on corals and eat shrimp and fish. They are very fascinating to watch though. I am currently setting up a 30-gallon single fish tank with maybe a watchman goby as a side kick.I am looking into a maroon clownfish or a dwarf puffer fish such as a leopard or Valentini. They will both eat shrimp and the puffer will eat other members of the clean up crew also, so the might not be considered reef safe. The puffers are occasionally known to nip corals, but I know no one who it has happened to nor have I ever seen it. That is just my input but I like single aggressive fish. Link to comment

Well of course, fish in the wild hunt basically the entire time they're awake, so feeding more often is better, but when it comes down to it they're not going to have any health issues from missing feedings a few times a week. Why would 2-3 fish antagonize each other? And if your filtration can't handle such tiny fish, I would question whether or not it would be sufficient long-term. Link to comment
-E- Posted January 2, 2017 Author Share Posted January 2, 2017 Just don't know what to believe. I keep reading that "peaceful" damsels will become aggressive as they get older. And every time I go to the LFS there's always at least one "peaceful" damsel laying dead on the sand. I got into this hobby because of youtube videos showing nano tanks with just an HOB. No sump, no fuge, no skimmer. Seems to be ok for my corals but I don't know how fish will affect everything. Running an AC50 with ChemiPure Elite and Polyfilter Pad. Link to comment

Most places don't understand or just don't point out the difference between an aggressive fish and a territorial one. Chrysiptera damsels can be territorial, whereas most Dascyllus damsels are just aggressive. Some fish are only aggressive to fish that are the same color or shape as they are, and others can be aggressive to any fish at any time. Beyond even genus and species, it can also come down to the individual fish. You can have a typically peaceful fish be a monster, or a typically aggressive fish be an angel. It's just something that you end up having to play by ear. Link to comment
Clown79 Posted January 2, 2017 Share Posted January 2, 2017 I have a 15g mixed reef with 2 clowns, shrimp, crabs, cuc. No issues, tank is run with an hob, heater, jebao wavemaker. Its about choosing compatible fish and keeping up on maintenance. Even large tanks with lots of fish will not succeed if those 2 rules aren't followed. You could do a purple firefish and goby Blenny and clown pair Clown pair and goby Some damsels Royal gramma and goby There are many options Check out Liveaquaria.com not only do they have a nano section but a compatability chart Link to comment
-E- Posted January 19, 2017 Author Share Posted January 19, 2017 This was all so much easier when I was a careless teen with 60g FW. Preferred choice: a pair of beautiful six lines. Con: tank is a 20L and could hit lid trying to spawn. Con: people say six lines don't stay paired. Reasonable choice: a pair of 2.0-2.5 inch Chrysiptera. Con: special order($$$) Con: not as attractive Possible choice: royal gramma pair. Con: builds nest by moving stuff around? Con: boring movement? Con: harasses invertebrates? My coworkers want me to get a clown pair. I don't know if they actually enjoy watching them, or just like the idea of Nemo with a girlfriend. One clown might enjoy my tank but I can't imagine a pair chasing each other the way my cave and hideouts are set up. Link to comment
jedimasterben Posted January 19, 2017 Share Posted January 19, 2017 It's actually Nemo with a boyfriend, as they will likely think the male is larger, but they're not It's your tank, not theirs, and they will likely oooh and ahhhh no matter what you put in it. If you're set on just a couple of fish, get a couple of starcki damsels and let them pair up Link to comment
-E- Posted January 19, 2017 Author Share Posted January 19, 2017 ...starcki damsels... OK. That's one vote for chrysipteras. Link to comment
Clown79 Posted January 19, 2017 Share Posted January 19, 2017 Wgen clowns pair, i have rarely seen them chase. Actually i find clowns "lazy". They just kinda bob in the water. My pair rarely leave their frogspawn Link to comment
FiveGallonSea Posted January 21, 2017 Share Posted January 21, 2017 Everyone is replying as if the OP has a 20 gallon, but it's a 20 liter. Just over 5 gallons. So 1-2 small fish would be the max. Link to comment

"20l" is also shorthand for 20 long. You could be right about that meaning liters, but considering that sixline wrasses are on his list, I'm thinking he probably means a 20g long. Anyways, OP, if you still just want a single fish (I'm sticking with the assumption that this is indeed a 20 gallon and not a 20 liter tank), you could also do just one dwarf angelfish. Like a flame angelfish or a cherub angelfish. They are beautiful fish, and in a small tank like that would be better off on their own anyways. Link to comment

Just didn't think a 20 long would be at an office.. Link to comment
debbeach13 Posted January 21, 2017 Share Posted January 21, 2017 4 x 39 watt light makes me think 20 long Link to comment
JLynn Posted January 21, 2017 Share Posted January 21, 2017 Yes, you're right. Just didn't think a 20 long would be at an office.. That is pretty big for an office tank, isn't it! Link to comment
Clown79 Posted January 21, 2017 Share Posted January 21, 2017 That would make a difference in stocking it. Lol. 20L or 20g Link to comment
-E- Posted January 22, 2017 Author Share Posted January 22, 2017 It's a 20g Long. Was advised against getting a pico as my first reef tank. Wanted a 30B but it would've been too big for the space. Link to comment
JLynn Posted January 22, 2017 Share Posted January 22, 2017 You're lucky you have space for such a big office tank! Link to comment

Thought about it but liveaquaria says they nip at corals. I want happy fish AND very happy corals. The six line is a beautiful fish but, with a shallow tank, I'm leaning toward the Crhysiptera damsels or royal gramma - especially if I can keep a pair (demersal spawning). Link to comment
jestep Posted January 23, 2017 Share Posted January 23, 2017 My picks for a 20g (not 20L) would be: Assessor basslet Single clown Royal gramma Spinger's damsel Talbot's damsel Chalk Bass Tobacco Bass Swissguard Basslet I would pick 2 from the list, 1 basslet and 1 damsel or clown and be done with it. If you're only picking a single fish, I'd do a damsel or clown. The basslet's tend to be too skittish without some dither fish that stays in the open. Link to comment
