I just started my new cichlid tank with 5 eureka reds. They are about an inch big and they seem to be doing well. a little skittish but thats ok. Now I am looking for some more fish to put in there with them. But I am a little confused on what I can or cant put with them. I really like the Aulonocara: maulana, stuartgranti, and baenschi but isnt it true that you can only have one aulonocara per tank otherwise they will interbreed?
