So....my daughter wants a guppy. I'm fine with that, I was going to set her up with a small tank, but then I thought why not stick it in my 10 gal with the cories. So I did some information gathering and found that guppies should be fed 2 or 3 times a day. I'm wondering about this because I've always fed all of my fish every other day from common tetras to my exotic rope fish. Do guppies really need to eat all of the time, and does that explain why the last time I had a guppy it kept eating my tetras???
