Added two 1.5” Uaru to my 125g and the single Severum that I have has been chasing them a bit and shimmying next to them. I had figured the compatibility would be fine, but maybe because they are close in size they are sparring a bit at least initially? The Severum is a bit bigger and was sold to me as Heros Severus although I think it may not be. Love the Uarus and Severum I’m only wondering how they’ll get along. The Uaru have stood their ground a couple times and the Severum doesn’t fight back when they do but for the most part the Severum chases them around.
