so i was impulsive the other day. i stopped into petco to buy a bucket of salt to do w/c's and i see this strange looking triggerfish in there tank where they put all there pred's they order in. it looked like a beast compared to the 2" niger trigger and the 3" volitan lionfish and it had already decided that it was hungry so it took a chunk out of the 2" red file fish. eye balling it i would say its about 4". i asked the guy working there what kind of trigger it was and he said it was a white line and had no info on it, so he called his girlfriend at home who googled it and she found info saying that max size 18" and semi aggressive. i say fine ill take it cause there arent many people in this area set up to accomodate an 18" trigger fish and i would hate to see it go to a bad home. paid $40 bucks for it and brought it home, did a google search myself and its not a white line but a yellow margin max size 24" and a little more than semi aggro. im hoping to get a little input from anyone that has had one and grown it to maturity as to what i should expect. im fairly confident that i would have no problems winging it but others personal experiences would be welcomed knowledge. thanks in advance
