I have 6 platies, 2 of which just gave birth recently. They also have ich (from the pet store) and I'm currently treating them with medication. The adults are huddled together in the corner. The babies are in a fry net in the same tank separated from the adults. The adults come out only to eat. Only 1 or 2 will come away from the corner huddle when it's not feeding time, but then they go back after a few minutes. Is this normal for them to huddle like this? Thanks!
