I've had mine for just about a year, it was one of the first additions. At the time, I didnt know they ate pods, not sure of it now, but I do see a big decrease. Try to spot feed it every now and then, they have a tendency to not see the food or for some reason just let it float by. So, for that reason I spot feed mine whatever I am feeding my other fish. All I can say is-- great fish, make sure you see it eat before you buy it, and if you buy 2 then we need to talk about the --- of them. HTH
