AboutRon Coleman Expertise I am an expert on cichlid fishes, particularly New World cichlids. My broader expertise includes the behavior, ecology and reproduction of fishes in general. (I am NOT an expert on Goldfish). Please do not use abbreviations, such as "my GT has a swollen eye" because I don't know what a "GT" is. The more clearly you can explain your question, the better chance I have of understanding what it is that you seek. I keep fishes both as a scientist and as a hobbyist and I currently maintain about 140 aquariums.
Experience I am an Assistant Professor at the California State University, Sacramento in the Department of Biological Sciences, and I run a website, called the Cichlid Research Home Page . I also write for many popular aquarist magazines, and I am editor of Cichlid News magazine. I am a scientist and I spend my time teaching fish biology, ecology, behavior and evolution and doing research on the reproductive biology of fishes, particularly cichlids. I do research in the laboratory and in Costa Rica, Nicaragua and Mexico. My main interest is understanding the evolution of parental care in fishes. I am interested in encouraging greater public awareness, understanding and participation in science.

Yes,
i agree with Ron, exept that I feed my tetras twice a day because I have very many and I wanted to insure that I feed them all without feeding too much and dirting up the tank. But where I live fish food that wount kill fish/bring up the pH levels is costly, so once a day is fine if you wish.
Also when you asked what type of fish you could add I found it hard to explain because, I have a 3 year old , elderly guppy in with my tetras and dont even bother it. But dont risk it. All I am saying is your in no way limited as to what fish you can add, because I have a soultion for tetras killing new fish. Buy a breeding cup (the ones that stuck on the inside of your tank) and put a new fish(or two if needed) that isnt being exepted into your tank in the separating cup. Over night the other fish seem to calm dowm and you can readd the fish. This has worked for me, and I hope to tell other fish owners about this 91% acurate procedure.
good luck,
=D
