Is this a stoma

I just saw little clouds being puffed up in my tank and took this pic of what was doing it. I think it’s a stomatella. Is that normal?

Stomatella breed by releasing eggs or something into the water column, it's normal.

I had two as hitchhikers on a frag plug, now I have about 10 big ones, love them.

thanks for the response. I tried to get a better pic of it but it seems to hate the paparazzi.
