hey i am relatively new to SA/CA cichlids although i did have an Oscar. and a breeding pair of convicts pink and black. but out of all of them i like my jack Dempsey the best but my question is is it possible to keep a male and female in a 30 or 40 gallon breeder. with just those two no others? cause i have heard cases were people have kept an adult pair in a 29 gallon.
