I recently purchased a fahaka at my LFS I’m concerned because he won’t eat the blood worms I give him he just bites them then spits them out. I’ve tried feeding him snails but he just kills them and doesn’t eat them he also won’t accept shrimp or clams. He’s just under an inch long his water parameters are 0 nitrites nitrates and ammonia about a 7.2 ph and a temp of 78-80 degrees I’ve only had him for just under a week so I might just be losing my mind for no reason but he goes after food and just doesn’t eat it so I imagine he’s hungry and wants to eat.
