To all, I recently purchased 5 Adult Anomalochromis thomasi. I am no quite sure of the sex of the fish I have. The dorsal fin on the fish all go to a point. One of the five is somewhat smaller then the other 4. They all are at least 3 inches or more. I would like to separate a possible "pair" into their own tank. Currently, all five are in a 15 gallon tank until my 45 is setup. Are there any distinct features to look for when trying to sex them like spots or body size??? What I have read is somewhat vague. Anyone with some suggetions would be greatly appreciated. Thanks, Phillip J. Ryti RYTIREEFS@JUNO.COM
