When Can They B Transferred To Main Tank, It Has 3 Platies 4 Catfish 1 Red Tail Shark

You've bred egglaying-fish? Wow.

In my experience the redtail shark will be the one to watch, if your not sure then don't reintroduce them just yet.

I managed to breed Jewel Cichlid's once, we ended up with about 200 of them. I've never managed to breed Gourami's though. Well done
