Hi, your welcome, just have a q on your mind just ask. Pink tail triggerfish are nice triggers. They are aggressive, but not that ggressive compared to other triggers. These guys are just as hardy as other triggers, and are pretty cool lookin. They get around 12-14 in. long.These triggers like the rest of them eat meaty foods (brine, krill, mysis, etc.), they like live, but you shouldn't because, when feeding this type of food it increases aggression, and the live foods are bad for your fish. It is fatty, and will give your trigger liver problems in the future. They get around 10 in. but I have seen larger ones around 12 in. in an lfs.I have had a white tip trigger in the past, when I just started this great hobbie. It was with a huma huma trigger. The huma huma attacked it, so I had to return the white tip. The white tip did not protect itself at all, all it did was swim away, I felt bad for the lil guy. Obviously this type of triggers are one of the nicer triggers. That is also what I have read a lot a couple of times. It eats the same things as the pink tail, and is the same as hardiness.
