I have a fry tank with molly, swordtail, platy, and guppy fry. They are all different ages, as my fish are always having fry. I noticed the other day one of my bigger platy fry was chasing my smaller guppy fry. A little later, I saw part of a guppy fry body at the bottom of the tank. Do bigger fry eat the smaller fry? If so, should I get another tank for the bigger fry? I don`t want my fry all gobbled up by the others.
