Fang blenny and a dottyback

[robitreef]

Do you think a bicolor dottyback will attack a fang blenny? If a fang blenny bites back, does it prove fatal to other fish?

They'll probably view each other as different, and spar without contact. The worst fights are usually where the new guy looks enough like the old guy to be perceived as a rival---ie, same body shape, mannerisms. But the fanged blennies can be pushy, ditto the dottyback.
