I scared of triggerfish more than anything in the ocean so far, haven't dived with bull and great white yet.
First time attacked, my husband/buddy got attacked first. We were at our safety stop, he was cornered until he decided to surface. I saw him getting into the boat and the trigger had gone. I didn't realize that it made a big U turn and went right to my head. The good thing was, he banged into my tank. It was a very loud sound and I'm still laughing until now thinking about its swollen lips.
It was a yellow margin/peach faced triggerfish, the second ugliest trigger.
The Ugliest, of course is Titan Triggerfish. We hold the record of being attacked three times in 45 minutes dive from three different Titan triggerfish! It was their mating season I guess.
First attack, we were just decending when the fellow chased buddy. Buddy swam to my direction, we were very close anyway, and we finned like hell while we were still trying to equalize. Lucky the attack didn't last long.
Second attack, by the most nasty bugger, it chased us for what feel like ten minutes (I guess it's really ten minutes), attacked and attacked again although I'm sure we had finned horizontally far away from the first point of attack. Looked like it was having fun, or maybe it hadn't gotten a bite of flesh yet.
We were super exhausted after that.
The third attack, we didn't see the trigger, it bit our fins, when we turned back and saw the trigger frontally swimming with full speed, honest, I was so fed up until I laughed, but of course I ran. It was so frustating, tiring until I had to laugh looking at its determination to bite us.
The three attacks were the highlight of the dive, we didn't do anything else.
Since than, our group always fin backward away from a Titan (facing it). Our DMs saw us doing that, and taught us how to predict them. If they are bitting the coral/eating or swimming, they won't attack. What you have to prepare is when they are stationary and looking at you with vicious eyes, then you'll have to run.
But I think for us, regardless what they do, we stay away from them the minute we see one.
Another reactions from DMs, one laugh at us, the other finned away faster than us.
We heard of nasty thing they do. Scar on my DM's face, I heard diver lost ear and..ouch..nipple. Don't ask me how.
Cheers!
