Iv'e seen clowns and lions work out fine,,, but some say its a matter of time till the clown leashes off. Theres a beautiful 125 aggressive post on site.. with both working out for a couple of years now. ImO .. if u want both, you can attempt it,, and if there are any signs of fin nippin remove 1 asap.. If it works out from the get-go I think it'll be fine
(Both great fish--- And look nice together)
