Fish/tank mates


I have 8 barbus(tiger-green-albino)3 odessa,4 gold barbus, 2 plecostomus,1 synodontis multipunctatus, 1 green severum,2 corydoras emerald green and 2 corrydoras sterbai. Just added a male baby jewel cichlid. Since i added him yesterday, he has been hiding behind a plant at the bottom.At the petstore, the told me that it could workout with all my other fish, but as i read, i'm scared that when he grows up that he will kill my other fish. I have lots of live plants and a few rocks and decorations. It's a 65 gallon aquarium, and i have put for now a seperation to protect 1 of my green barb's that has only one eye, so if i see that it doesn't work out, i could transfer all the barb's on the otherside, but since i only have 1 jewel cichlid, do you think it could work out fine? If you want, i can take a picture of my aquarium if it can help out.

ANSWER: Hi Tricia,
  It is impossible for me to say for sure.  If you get a second jewel cichlid of the opposite sex, then I could say for sure that it would not work out, because then the jewels would mate and at that point, they would "clear out" the tank.  I have my suspicions that as your jewel gets older, particularly if it is a male, he will start to get territorial on the off chance that someday a female should suddenly appear... fish are forever hopeful...

My Jewel cichlid died 2 days after i put it in my tank, the fish was weird... it would just stand there and even go right in front of my severum, bump in my plants and rocks... anyways... i reserverd another jewel cichlid, but a female, do you think it would be better? if not, what kind of fish that gets at least 4 to 6 inches would you recommend for my fish tank? i want to keep my barb's as i still find them cute, but i want another fish that gets big and goes well with all my fish.

Thanks again!


Hi Tricia,
  I think you are trying to do something that won't likely work.  If you put a large fish in there (4-6 inches) it is going to cause trouble for your other fish.

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.


I am an Associate 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 was editor of Cichlid News magazine for several years. 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.
