Niger Trigger, in a reef tank?

[justinl]

Well, first you have to realize that there are two kinds of triggers. those with down-turned mouths who specialize in benthic feeding, mostly on crustaceans, and those with upturned mouths who specialize in feeding in the water column. The first group includes the may-eventually-go-psycho-and-kill-everything triggers like clowns and undulated among others. The second includes the more peaceful crosshatches, nigers, pink-tails, blue throats, etc. Obviously you would want to pick one of the latter.

Another thing you have to consider is that they swim. a lot. and fast. big triggers can easily snap corals so you may have some unintentional fragging going on as well as some corals just being knocked over if they aren't secured well enough (zip ties, big rocks, and superglue come in handy here).

You may also want to think hard about putting a trigger in an acrylic tank. Their skin is like chainmail and can put a lot of scratches in your front glass if they swim there often (associating you with food). The bigger the tank, the less likely this is to occur I think; but you would probably need a VERY large tank if I am right.
