what kind is it? Look for black spots or deterioration on it. Don't take it out of the water, the air gets trapped in it and it will surely die.
You can cut off the bad spots if you see any with a sharp razor. Only a few cuts per razor because it will dullen the blade and you may damage the rest of it.
Also they like low light and are filter feeders. Pytoplankton works well.
