Do wrasses harass your stomatellas?

I think i got some stomatellas to reproduce in my fuge. I put a large one (thumbnail size) into dt and my wrasse wouldnt leave it alone for even a second. Kept nipping at it so i moved back to fuge. These guys clean my fuge all day i want to add some to dt does this occur to anyone else?

Btw its a sixline (my little brat of a fishchild)
