Humu Trigger hits rock

Just wondering if anyone knows why my Humu Trig goes up to my live rock and spins his body into the rock, i noticed this morning in the middle of his left side he has scratched himself(his dark color is scratched away). sometimes he will actually do a full barrel roll..Thanks

 

What do you mean by spinning?
Scratching himself in the rocks?
Could be signs of ich or any other parasite.

 

he will go up to the rock and scratch his side on the rock buy doing a barrel roll motion, twisting his body into the rock when he is right next to it so it scretched his side. i have a picture of him doing it but not sure how to post another pic on this thread. k i added a pic of him doin it, sorry pic is from my phone, its not to great..thanks again

 

I agree with elweshomayor. Could be ich, although I have seen fish that are not infected do this too. No different than you scratching your arm I would guess.
