Canary Blenny attacking snails?

[ItsNiQi]

I asked my LFS for a fun and peaceful addition to my tank. The guy immediately told me about this Canary Blenny that he had. As soon as I introduce him to my tank he starts to bite all of my snails! I’ve looked everywhere and I can only find posts about lawnmower blennys doing this. Is there anything that I can do to slow down the aggression? Someone told me to up the feedings but as soon as he’s fed he continues to harass my my Mexican Turbos, Nassarius and conch!

That's not behavior I would've expected. Maybe one of our #Fishexperts will be able to help.
