I think anytime you get yourself a trigger it's a gamble against time,.... Certain triggers may be a little less of a risk than others but they pretty much will eat up all of your inverts and may or may not go postal on their tank mates,... But on the plus side they are characters and are so cool to watch,... I agree that the blue throat seems to be the best suited and the least of a risk,.. I think the larger the tank the better they'll be, they tend to be territorial and aggressive but in a larger setup they seem to be less agitated ,... Greg has one in his 300 gal
tank that seems to have blended in and so far has been a good citizen. ... Good luck , they are definitely cool .
