A few days ago I didn't think anything of it. Now i'm worried (agian.) The puffers eyes are clear and look normal, but it seems like he can't see. He spins around at the surface of the water a whole lot. I tried to hand feed him, and he kept swimming around near my hand, spinning around, like he couldn't find the food but knew he it was around. I coaxed it near him, and once he found it and ate a big chunk of Mysis shrimp coated in blood worms, but that was all. Anything I can do? Do you think he really is blind?
