Have some questions. Currently i have a 220 thats been up and running for a couple years. It has some soft coral, 3 clowns, and two wrassses in it. I want to convert tank to predator tank. I added a snowflake, and undurated trigger and a lionfish. Lion and trigger are small 2 inches Id way. I know once they get bigger the clowns and probably the wrasses will have to go. Id like to add a dogface puffer, harlequin tusk, and possobly some other triggers, possibly grouper? What kind would do best with the lion and the triger. And I know its a large tank but these are large fish, what would be my limits as far as overloading? Thanks
