I waited until Jake got some small, I mean really small hippo's. I have a 75 and my hippo was the size of say a quarter. I'll trade him back before he gets too big and start all over with a tiny one.
When I switched I cooked my green slimer and my red digi, I just ordered new t5s and was talking to Julio at aquacave and he said next time I change bulbs to do exactly what Daniel said to do.
I got some blue hornets and kedds reds from J.R. and they were opening in the bag! Very healthy very nice. I would suggest you jump on the frags he has. I promise you'll kick yourself if you don't. Thanks again J.R.
