So about a week ago I got 3 platies to go along in a 5 g with Fred, and STUPID me, i got 2 different kinds. (I believed the Petco guy.) Anyways, the one that didn't come from the same tank had a small fin and i noticed that her tail was chewed up the day after. Now, I dont know if the other fish did this or I bought the fish like that. But it stopped eating and stayed at the bottom of the tank. When I came home today, I noticed it was dead
. (Will be doing a water change!) The other two are completely healthy, btw.
So I guess my question/concern is, if I go out and buy another fish of the same exact kind, will the other ones be mean to it (haha) or should i get two so the new one has someone to be with? Because i know these fish need to be kept in schools..
