Is this possible? my 8" Red Spotted Severum and my 4" Gold Severum, both male are cleaning rocks together and will not leave eachothers side at the bottom corner of my tank (the gold severum every now and then darts out to chase off other fish then comes back into position), is it possible to get a male/male pair? i really hope not as i made my tank all male to stop breeding in the first place!
