I picked up a sea hare at my LFS today and he’s been munching away at my GHA. I understand that when my tank is algae free I’ll have to send him away but he’s doing great for now and I have plenty of algae. I’m kind of worried though because looking at pictures their hole doesn’t look this big. Is this normal or is he injured or dying? I must say he is moving a lot and very active and eating just worried maybe overthinking.
