Fish/Aquarium Setup


I'm setting up my first tank, and I'm wondering if these fish will be compatible with each other.

I have chosen:

1 Angelfish
2 Cory Catfish
2 Upside down Catfish
4 Cardinal Tetras

The tank I want to get is a 29 gallon. Will these fish be compatible with each other, and is the tank big enough? Thank you!

Hi Anthony,
  In general, they should go together though I am a little concerned about the angelfish with the cardinal tetras, particularly if the angelfish is large and the tetras are small.  Be sure that you have lots of plants (plastic or live) in there to break up the space and provide hiding spots should a fish need a place to go.

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.
