So I recently added a 12" red scarlet pleco to my 210g. I was told it would be a dominant pleco and would get along with other unless anything tries to occupy it's claimed space. Well they weren't kidding, it's peaceful unless you want to try and be in it's space, then it will chase whatever off. So now it's the dominant fish in the tank. Got to witness my 13" pike try and keep it from taking it's space and the pleco won easily. Now they all know to let it be. Anyone else keep these?
