I just rescued a scopas tang he is still a juvenile I saved him from the mighty porcelain thrown , he is a little over 2 in he is one of the most aggressive tangs I've seen , I don't plan on keeping him long due to his aggression , my tank is fairly mellow and this guy seems to just pick fights , I have 2 wrasses in the tank a lunare and a red coris they seem to back the tang into a corner till he mellows out , they not once touched him they just seem to be the tank police keeping things quiet , I don't think a kole and a scopas would fair well together , just for the reason the scopas seem to be nasty against tank mates ,
once I find a home for the one I have he will be packing his bags
I have aggressive fish and they seem like angels compared to the scopas
if you plane on keeping him with the fish in post 3 I see a blood bath
