So I got a common pleco a week ago and I’ve been worried about him not eating. He loves his driftwood but doesn’t touch the algae waffers? I thought I’d get him doing good on those before I started introducing new foods to his diet. I came in today and he was doing this? He was still breathing and when I touched him with a net he swam away and stuck to the tank like normal. Is this common or should I be worried?
