my hippo tang can't seem to find the food and was losing weight , I put him in a box hanging in the tank and he is able to feel for the food . any suggestion??
So he's actually OK if there weren't any other bullies around. Heh, he was the mighty hippo, the king of the tank, The lord of the land, but that urchin spine in his eye...Now he is as meek, as feeble, as a lonely fire fish.
This may or may not work, but I've had some success restoring a fish's eyesight by doing daily methylene blue baths: https://humble.fish/methylene-blue/
