Hi all, this is my first post here, i have 2 turtles, male and female, in a 350litre tank, with a pleco. I was looking for advice as to any compatiblity isues anybody may know of keeping them together, as iv noticed that in a smaller tank they started nipping on the poor guys fins, all be it this was in a 90l tank which has now been adequately increased,, and im hoping the space was the cause,(teritorial). Any help would be kindly appreciated.
