I just rescued a male melanochromis along with a peacock eel. And the cichlid has a cloudy film over his eyes... Is this permanent? Right now I have him in a 10gallon before I put him into my 75g. Is there anything I can do to fix this, to make his sight better? he still knows when I come up to the tank and begs for food but when I put the food in the tank he always misses I practically have to put it right in front of him.
