problem with clowns

[SNAKEMANVET]

I have had them for about a year,they are true percs.They started with a couple of big lumps forming first, then they turned red.They are eating fine and no heavy breathing.The fins look good.The problem didn't occur until they started going into the anemone.I cannot find a id for the anemone.Hard to get pics,they stay near the anemone at the back of the tank.
