You might want to check the par ratings at different depths in your tank. The club has a par meter, you could check it out. Might also be that the bulb is changing spectrum and needs to be replaced. The ones you say are doing well are easier to feed and probably catch some food when you feed the rest of the tank. Just a guess...
