I have a young male umbee I just moved to a 300 gallon, he’s around 5.5 inches and starting to show some nice colour. I have another smaller male in there that is being bullied and I’m going to have to sell but is there any tank mates for him? I was thinking maybe a female festae or female dovii, maybe a pair of convicts or some Bala sharks and maybe even a catfish of some sort. Thanks
