Appearance

From before birth, their eggs are demersal and adhesive and attach to substrates via a filamentous adhesive pad or pedestal. The bluestriped fangblenny can attain around 90mm in length. Two distinct colour phases of this fish are present; blue with a black stripe from snout to tail, or orange with two narrow blue lines from snout to tail. Unlike most blennies, the bluestriped fangblenny is free swimming. Adults inhabit clear, coral-rich areas of lagoon and seaward reefs and it is fairly common on both coral and rocky reefs, usually occurring singly or in pairs. They are known for being aggressive and feed on skin, mucus and sometimes other fish scales. They bite divers when alarmed.

Behavior

The fangblenny is a specialised mimic of juvenile bluestreak cleaner wrasse. Those fish serve as cleaners to larger host fish, which attend to have ectoparasites removed. The fangblenny does no cleaning, but bites the host fish and leaves. Its opioid-containing venom helps it escape, as it gives a pain-free bite which also dulls the host's reactions.
