My pair bred in my 240 2 weeks ago. I got about 100 out and put in a 10 gallon. I accidently left one small convict in there and he had a feast. I only have about a dozen left. The ones left in the 240 were eaten by tankmates I assume. They are gone. I'm gonna set up a 75 for just the sev's and see if they do it again. I'm pretty confidant they will.
