Well not much has changed with the challenge fish. Their growth rate has slowed down. They are being fed 4 times a day with beef heart- seafood mix, brine shrimp, and pellets. All are eating well and there seems to be no problems with any of them. The only question I have is with them breeding. The 2 that have been breeding were at it again the other day. I did see the smaller one laying eggs but the other one started eating them right away. Since it didn't lay eggs am I safe to assume that its a male and whats with the egg eating. Oh well , maybe next time they will get it right.
