Its not uncommon to have a stone ingested, you might try feeding the fish a pea, frozen is usually easier than raw.
If that fails, then a bath in epsom salts is the next best approach.
With out knowing the water conditions, ie ammonia, nitrite etc, and the fish showing no signs of a disease, I have to assume its an injested problem. However it may be something else, but its a place to start. Two O's in a four foot tank, is very overstocked, so it could be related to a water problem, can you tell me how offten you change the water in the tank, and how much when you change of the tank water , when you do a water change.
Also what type of filters do you use on the tank?
