Tag: Carpet Eel Blenny (Congrogadus subducens)

This unusual fish is easily mistaken for an Eel, and even its common name is doubly misleading.

Commonly known as the Carpet Eel Blenny due to its long, slender appearance, it is neither an Eel, nor Blenny!!. It is in fact a member of the Dottyback (Pseudochromidae) family, the closest relatives of which are actually the Groupers.

Carpet Eel Blennies have the ability to change colour, although it would seem that the "mottled" green/brown colouration is the most common.

They are aggressive carnivores of small reef fish and attain a maximum length of approximately 50cm.

Preferring sheltered inshore locations, Carpet Eel Blennies can most often be found peering out of crevices, or amongst seaweeds and grasses at Mae Haad/Koh Ma.

They have also been found occasionally amongst the debris beneath Chaloklum pier.
