for the benefit of all members, here is my tank with oscar and an aro.
i am baffled why my aro keep on picking Survivor, the lone lutino oscar.

Mine still has a nip here and there. it can't catch the clowns so miss them by miles. parrot not so lucky but it isn't doing any damage. like yours its mainly a side nip and chase. so have restocked with oscars now. )))
