i have one convict, a female in my 30g. now she can be a real bugger but she is very cool too. she comes to the glass and watches everytime someone is in the bedroom, if u sit and look at her she'll swim back and forth showing off her colors. her belly is a vibrant orange and if she's in a mood her dorsal fin is a really pretty iridescent blue/green. i know it's hard to have this fish with anybody else and she seems like she'ld be able to pump out the babies cause she's always laying eggs on our driftwood. all the lfs have tons and people buy them only to bring them back, usually with babies. they are a sassy fish but still an interesting and beautiful specimen. I mean the name should give away their attitude problem black convict!
