I agree with esshup have you seen how big that fish food is. I thought it was meant for lmb 1-2 pounds and up. i'd just feed them what your feeding the other fish it won't hurt anything. another option might be to break up the aquamax lmb into smaller pieces so the fish can eat it but I still think you'll be fine just using what your using for the other fish.

Sarcasm...yet another free service I offer.
