Hi! I’ve had an albino rainbow shark (William Sharkspear) for about 9 months now. He was just under an inch when I got him and now he’s huge, almost 5inches. My question is how do I know if I’m over or under feeding him? He seems to be a little chunky to me but he attacks my tetras if I cut back his food so maybe he’s under fed? He’s my first shark so I’m kinda out of my depth here. He eats 1 hikari algae wafer every other day, on the days he doesn’t get the wafer he gets a bit of freeze dried brine shrimp. He’s camera shy so getting pics of him is nearly impossible (I’ll try again later). Is that a good amount of food for him?
