hey guys I want to set up a 90 gallon tank as a non aggressive community tank, I think I want to keep it South American mostly and I want to add a black ghost knife fish some stiphodon goby and a school of fish probably some kind of tetra, I was wondering if I would be able to put in some angelfish and also a couple of the non aggressive South American puffer fish, I’ve been reading that the angels and puffer May mess with some of the other fish but if I can’t put them in I’d be looking for something else to include in their place (I know the knife will outgrow the tank but that won’t be a concern for a while and I’m trying to make angelfish work because my girlfriend loves them, the puffer fish would more be for me but if they will kill the other fish I just won’t have them)
