So I got these babies about a month or so ago. They're about an inch long and I've noticed their bellies getting bigger. The friend that gave them to me believes that the mother is a Platy she has in her tank (orange one on the right). The babies have the same black flecks on them as well so I believe it could be the mom as well. (Not related) that one black fish she has with the shredded fins, he's been like that for a long time and eventually the fin damage stopped getting worse but how can she be sure it isn't fin rot? Please ignore the yellow circle that was her showing me her snail.
