I have an 80g FOWLR. 3 cleaner shrimp, blue jaw trigger, powder blue tang(R.I.P.-ich), a kole tang(R.I.P.-ich), engineer eel, a red spotted goby, a green corris wrasse, 4 green chromis, a sea urchin and crabs and snails and a couiple corals. The blue jaw is super cool hell spit at ya if the tank top is up. Its crazy he plays with the sea urchin. And pulls in "the cave" every little bit so the cleaner shrimp can get at em! Its my understanding that he is one of the more dosile triggers though....
