I have had him for 2 months now. I was expecting an inch by now, he's currently around 2 inches. Ive been feeding him Omega One, NLS, and hikari. I need some new ideas please, preferably get them from amazon. He gets 2 50 percent WC a week, sometimes but rarely 3. He's in a 60 gallon btw. What can I do to speed this up?
