Im looking to add fish to my 75 gallon tank. Right now I have 10 gold pristella tetras and six marbled hatchets. Im looking to add some more fish and thought a pair of angels would make a good centerpeice fish. Im also looking to possibly add one or two bristle nose plecs. My main concern would be the Angels and the hatchets. I also wanted to add a few pictus cats but from what ive read would probably be a bad idea.
