I took the dad out after about a week and left them with just the mom. I figured the dad wouldn't recognize them since he already paired up with the other krib I had in my 29. Plus the fry are getting around pretty good now. They're all over the tank. They're about 2 cm long right now, and starting to look like actual fish. I just drop in 1/2 an algae tab in there and do a 10% water change daily.
