Wait. Since when do triggers have a dorsal fin?

So I’ve had a sargasm trigger for almost a year now, but the other day my son called out “Daddy, the trigger thinks he’s a shark!” I went to the tank and discovered that the trigger actually has a dorsal fin that he normally keeps hidden. For some reason he decided to put it out, but I had never seen it before. I didn’t even know he had one.

They have a thick/strong dorsal spine that they trigger and use to wedge themselves into crevices when attacked right?

If I'm not mistaken I think that's where the name Trigger came from. That dorsal fin acts like the trigger on a gun. Sometimes they'll use it to secure themselves among the rocks when they sleep.

Correct, the trigger allows themselves to wedge in rockwork, for sleeping or hiding

Hahaha, I guess so. I can’t believe I’ve had him for this long without seeing it before
