My male guppy is like a vacumm, he eats and eats. I have bottom feeders so I use wafers. He eats his flakes, then goes for the loaches food. He is so swollen he looks like he could pop! The only thing I can think of is to seperate him at feeding time, but he's in a planted tank, and it would not be easy to catch him-especially after the first time (he won't trust me anymore). Any suggestions?
