So I had a bunch of baby guppies and I am getting rid of the adults and don't want to wait for the babies to grow up. So I put them in my 55g with 4 angels, a BN pleco, and a betta temporarily. So I put them in there and my betta went after them immediately, but my angles aren't going for them. One went right pas their sight line about an in. away and they just stayed there. They are big enough to eat them, they are newborn guppies and year and a half angels. Why wouldn't they try to eat them. They have been awake for 20 minutes prior and went for the flake food I put in.
