i have. never buy one that is young, as they grow they can turn very mean. buy one at least 9'' long to be sure it is mature and wont turn, because once a trigger reaches maturity they usually keep the same level of aggression. so i would find a large one watch it interact with other fish to make sure its docile(docile is what you want) if you see it chasing fish around its probably not the one you want lol. i would still add the trigger last depending on what you want to put in tank. but if it is going to be your meanest put it in last or don't add new fish after a week, clown triggers are not overly fond of new comers lol
Triggers and bamboo shark together sounds like you're asking for trouble.
The grouper will try to eat anything that's smaller than it, and oftentimes wrasse and lions are just not suited to fight back. You know the lionfish problem in Florida? Groupers have been documented to swallow lionfish whole there as well.
The thing is most people don't understand what "small enough" means. Nor is it clarified anywhere.
Yeah. Pretty much. Though groupers, anglers, lionfish, and lizardfish are particularly troublesome as the tankmates you keep don't need to be that much smaller than them in order for them to swallow them.
I'm surprised the tang hasn't gotten stung yet. Besides, dwarf lions are too small to show their lionhood. Get a Volitans and just watch him gobble every little guy up.
