our first 29 gallon had 1 clown, goby and 2 firefish and a clean up
We had them for 2 years and everyone seemed happy. We moved up to 40 since and they are still there, happy I hope with a couple of new tank mates.
Our il informed neighbor had a 29 and was insistant on getting the pretty fish. And the LFS was happy to oblige. Needless to say after about 6mos the beautiful yellow tang got bigger and you could tell he was stressing out due to confinement. He almost paced back and forth very crazy like. He died soon after that. Neighbor couldn't figure out.
He knows now.
