I was thinking of getting a pair of either maroon clowns or a pair of clarki's (sebae) clownfish. Ideally I'm wondering if it would be possible to keep 4 ( a pair of each) safely in my 120 gallon tank. I have 2 anenomes , one seabe and one bubble tip. I know your not supposed to mix clown pairs but is it impossible? Would another species of clowns go better together? Any input is welcomed. Also does anybody know where they sell onyx clowns? Thanks!
