Trophic Strategy
provided by Fishbase
Inhabits clear, coral-rich areas of lagoon and seaward reefs. Hides in deserted worm tubes or other small holes when alarmed. Feeds on the skin, mucus and sometimes scales of other fishes by quick attacks. In common with other mimetic fish, resemblance of fangblennies to juvenile bluestreak cleaner wrasse, Labroides dimidiatus, allows them to actively hunt in areas where adult cleaners are common thus, indirectly improving their feeding opportunities (Ref. 75867).

Biology
provided by Fishbase
Adults inhabit clear, coral-rich areas of lagoon and seaward reefs (Ref. 1602). They hide in deserted worm tubes or other small holes when alarmed (Ref. 1602, 48636), bite divers occassionally (Ref. 90102). They feed on the skin, mucus and sometimes scales of other fishes by quick attacks. Oviparous. Eggs are demersal and adhesive (Ref. 205), and are attached to the substrate via a filamentous, adhesive pad or pedestal (Ref. 94114). Larvae are planktonic, often found in shallow, coastal waters (Ref. 94114). Juveniles mimic the cleaner wrasse Labroides dimidiatus (Ref. 9710). According to Ref. 53299 they are facultative mimics that change their color: at cleaning stations they mimic the cleaner wrasse and attack unsuspecting customers; elsewhere they adopt an alternative color and striping pattern to conceal themselves among fish shoals from which they can strike at passing fish.

Bluestriped fangblenny

Bluestriped fangblenny in a coral hole
Plagiotremus rhinorhynchos, commonly called the bluestriped fangblenny, is a species of combtooth blenny found in coral reefs in the Pacific and Indian ocean. This species reaches a length of 12 centimetres (4.7 in) SL.[2] It is also known as the bluestriped blenny, bluestriped sabretooth blenny, blunt-nose blenny, cleaner mimic, tube-worm blenny or the two-stripe blenny. They hide in deserted worm tubes or other small holes.
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.
Description
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.
Aggressive mimicry
Bluestriped fangblenny mimic the juvenile bluestreak cleaner wrasse, Labroides dimidiatus, to enable them to loiter at cleaner stations and dupe clients waiting to be cleaned.[3] Their success in this aggressive mimicry is, like Batesian mimicry, frequency-dependent: it works best when the mimic is rare compared to the genuinely symbiotic cleaner fish.[4]
The fangblenny has an unusual adaptation for biting and escaping without being pursued: its bite is pain-free, as it has a venom containing morphine-like opioids, which dulls pain and reduces blood pressure. The fall in the host's blood pressure makes it lose co-ordination, just as a human feels dizzy when blood pressure is low, giving the fangblenny time to escape. This may explain why other coral reef fish mimic the fangblenny.[5]
