I picked up 4 male platies today and they seem to love their new home! Also, they have taken the attention of my aggressive guppy off of the injured one, but I'm not sure the injured one will recover as he is missing a large portion of his tail. The aggressive guppy is still a puzzle to me and he keeps nipping at the platies even though they are bigger than he is, but I don't think he will harm them much.
