Peaceful community tank-Kole
Aggressive-trigger lionfish. That damsel, which is aggressive is too small (if not now real soon) to live with the trigger and lionfish.
Volitan lions cannot be kept in 90g tanks. 125+ for them as they get to be a possible 15in. You could do a dwarf lion if that damsel was gone. I would say (and FTMMWS) that no trigs should be kept under 125g. The kole tang would be perfect.
