Saltwater Fish
Midas Blenny.
The Midas blenny is a golden, 5-inch eel-shaped reef fish that splits its time between rock-perching and open-water swimming — and in the wild it mimics the color and movement of yellow Anthias to blend into their shoals. Reef-safe and full of personality; give it plenty of crevices and a 30-gallon-plus system, and keep just one unless you have a confirmed pair.
We keep this species at our Erie store. Come and see it in the tanks, or call (814) 456-9445 and ask what we have in right now.

Good tank mates
The Midas blenny is reef-safe and generally peaceful, doing well with tangs, clownfish, wrasses, cardinalfish, and other easygoing reef fish, and it likes a perch and caves to dart into. It can get nippy or territorial toward other blennies, dartfish, or similarly shaped bottom-dwellers, and toward its own kind unless it is a confirmed pair, so avoid crowding it with lookalikes. It does not bother corals or ornamental shrimp.
Good to know
The Midas blenny is an active mid-water swimmer that often shoals with and mimics the color and movement of yellow Anthias to blend into their groups.

Ultra Black Ice
Peaceful and reef-safe, clownfish anchor to a host anemone and create no territorial overlap with the rock-perching, water-column-swimming Midas Blenny.
Lyre-tail Anthias
In the wild the Midas Blenny mimics Anthias coloration and actively schools with them during open-water zooplankton feeding, making this one of the most naturally compatible pairings in a reef tank.
Banggai Cardinalfish
Calm, slow-moving, reef-safe fish that hover near coral heads and create no feeding or territorial competition with the active, perch-hopping Midas Blenny.
- F
Flame Angelfish
A small, reef-tolerant dwarf angelfish large enough (4–5 inches) that the Midas Blenny will not harass it; both species suit the same 30-plus-gallon reef systems and occupy different microhabitats.
- F
Fairy Wrasse
Peaceful, active open-water planktivores that share similar saltwater parameters and reef compatibility; they occupy the mid-to-upper water column without competing for the blenny's rock-perch territory.
