The trigger has been in the tank for 4 days now and has never even touched my corals. It's behaving very good. Doesn't bug my other fish and my 3 shrimps are all alive and well. The smallest shrimp I have is about 1.5 inches (cleaner) and the trigger doesn't mess w/ it, so I'm safe there.
I tried to feed it every other day so far, to see if it'll pick at anything when I keep it hungry, and it doesn't, so that's a good thing also.
I do keep losing my hermit crabs, but that was happening before I put the trigger inside. I think my coral banded shrimp is killing my hermits, and there's no way i can catch that SOB and take it out of the tank
I'd love to have more triggers in that tank, but don't know of other ones that may be reef safe.
