*Note: There are two "Koi-Lo's" on the pond and aquaria groups.

He almost looks emaciated. Is he eating? If you don't want to remove the
new rocks can you move him to another aquarium?

He doesn't pig out like the females because he's usually guarding his
nest but he eats well daily.

* Have you considered he may just be growing old? Old fish often get that
"underweight" look. If he's young you can also try to give him a break from
breeding by removing the females - and see what happens. If he's the only
one of several fish affected then it's surely not one of the rocks.

I could move him to another tank but I'm
not opposed to removing the rock that is causing the problem. He's the
main focus of the tank so I want to get him back into good health.

Koi-Lo....
Aquariums since 1952. Frugal ponding since 1995.
