Was it hard to catch them in the tank after the morphed? I find they grow much bigger and faster in viv but can be tough to catch after morphing. I started trying g to pull them right before the front legs pop and moving them. Makes it much easier. If you have frozen tubifex worms over there you could throw some of those in the food rotation as well. Mine go nuts over them and seem to I crease growth rate compared to fish flake
