(Last Updated On: )

The Midas Blenny is a superb candidate for a reef tank. It’s a stunning, deep golden-yellow with a shadow of blue beneath the chin and vivid, blue-rimmed eyes. When swimming, the movement they use could be very eel-like.

In this article, I  am going to talk about Midas blenny care, tank size, lifespan, reef mate, diet, stresses, hiding, and lawnmower blenny, etc.

The Midas blenny, scientific name Ecsenius midas is often known as the Golden Blenny, the Lyretail blenny, and the Persian blenny.

They’re combtooth blennies that feed on plankton and are sometimes seen swimming above the reef.

They don’t seem to be widespread however in sure areas there could also be massive numbers of them.

Midas blenny classification

Phylum: Chordata
Class: Actinopterygii
Order: Perciformes
Family: Blenniidae
Genus: Ecsenius
Species: E. midas

They have been first described by Starck in 1967 with the holotype being from the Amirante Islands within Seychelles.

The Ecsenius genus is exclusive amongst blenniids in that they’ve two units of canines tooth, one set on every jaw.

Unusually for fish that feed above the reef, they haven’t any swim bladders that means that they should preserve swimming and can’t stay stationary within the water desk.

This blenny will respect a minimal tank of 30 gallons or bigger with quite a few rocks on which to perch.

Typically, the Midas Blenny will vex small planktivores and has been identified to nip at firefish and gobies.

Bigger tanks are advantageous as lots of Midas Blenny’s aggressive habits traits appear to narrate to a confining tank scenario.

Not like most blennies, the Midas Blenny requires a meaty weight-reduction plan together with finely chopped crustacean flesh, mysis and vitamin-enriched brine shrimp, together with frozen herbivorous preparations, micro, and blue-green algae.

Midas blenny in the wild

The Midas blenny appears to desire explicit environments, they’re practically at all times discovered the place there are massive numbers of Sea Goldies (Pseudanthias squamipinnis) though they might now and again be seen with the Pink-bar Anthias (Pseudanthias cooperi) and the Fusilier Damselfish (Lepidozygus tapeinosoma).

Actually they prefer to swim inside shoals of different fish which feed on zooplankton.

They’re mostly seen under 12 meters and above 15 meters and the realm the place they’re prolific is on the highest of the partitions on the east coast of Mafia Island on Dindini Wall.

That is an unprotected reef near the coast with a powerful present and wave motion on the floor which works in opposition to what’s reported elsewhere, however that is the place they’re at their most prolific with massive numbers being current.

In different areas, they don’t seem to be widespread.

Even when prolific they’re seen singular, however within the areas the place they’re prolific they continue to be aside by roughly three meters and nonetheless seem territorial, seldom interacting with one another.

hey mimic the feminine Sea goldies (Pseudanthias squamipinnis) pictured above and swim throughout the shoals of those fish whereas feeding.

Though one can decide them out from a distance fairly simply, to {photograph} them swimming shut up could be very troublesome as they’re very energetic and have random swim patterns.

This most likely on account of their lack of a swim bladder. They appear extremely territorial and if one returns to the identical spot, the identical specimen or an equivalent one can be in the identical space with the identical gap that it darts into once they really feel threatened.

Jacob Dafni and Ariel Diamant put ahead in a fascinating article that mimicry which they time period faculty oriented mimicry differs from Batesian and Mullerian mimicry.

Starck who described the species believed that they have been the mimic and obtained safety from the shoal due to the problem a predator has in selecting them out which is sensible.

After many tries photographing them free swimming in these areas the place, they’re prolific with many feminine Sea goldies around.

There seems to be no interplay between the 2 species and the Midas Blenny seems to swim throughout the shoal of feminine anthias at excessive velocity after which make quick darts out to feed on the planktonic matter.

The feminine Sea goldies having a swim bladder sit in a secure place and the Midas Blenny already having some velocity is quicker off the mark.

Additionally, they appear quicker swimmers total than the anthias and are simply capable of out-compete them for passing prey.

After the swim decreases down nearer to the substrate they usually intermingle with Cardinalfish and positively darken their colors at this degree however that is prone to camouflage in opposition to the background through a yellow line/patch does seem within the entrance of the body.

Arduous to say, one can draw one’s personal conclusion off of the picture under, actually not a great mimic although.

Midas blenny Description

Not like many of the Blenny family, the Midas Blenny simply falls beneath the reef secure class. This enticing yellow fish feeds totally on zooplankton and never algae and spends most of its time perching in small holes and swimming within the water column.

Moreover, males and plenty of females have elongated higher and/or decrease caudal lobes; no different Salariini nor Blenniini possess this characteristic.

Additionally, Ecsenius lacks circumorbital bones, whereas all different members of Blennidae have 4 circumorbital bones.

Lastly, aside from just a few members of Nemophidinae, solely Ecsenius have their lateral extrascapular bones fused with the pterotics.

Ecsenius bimaculatus is among the smallest members of Ecsenius. The most important feminine collected has been 27 mm, whereas the biggest male was 32 mm.

Though this species is unusual within the wild, the pure vary discovered solely throughout the Philippine Islands makes it out there throughout the pastime now and again. Photograph courtesy of Jack Randall (left) and Darren Hoglund (proper).

Though one subgenus was used up to now to assist differentiates Ecsenius midas from all different members of the Ecsenius genus, this subgenus, Antiblennini is now not in use.

Springer (1988) acknowledged the dearth of “apparent synapomorphy which outlined all different species of Ecsenius to the exclusion of Ecsenius midas.”

As such he felt a minimum of two extra subgenera could be required to take care of nomenclatural consistency, so till additional analysis was capable of kind higher interrelationships throughout the genus, the very best transfer was to rethink his earlier notion of E. midas being a monotypic subgenus and thus Ecsenius at the moment isn’t subdivided into subgenera.

Midas blenny Diet

Feed a diverse weight-reduction plan together with finely chopped uncooked shrimp, chopped crustacean, mysis shrimp, flake, and pellet.

Unusually for the genus, the Midas blenny is a planktivore and feeds on zooplankton though they do complement their weight-reduction plan with algae.

Midas blenny Habitat

The Midas Blenny happens from the east coast of Africa as much as the Gulf of Aqaba and eastwards to the Marquesan Islands.

They’re normally discovered from 12 to 18 meters however are reported as deep as 40 meters.

Midas blenny Appearance

The Midas Blenny obtains its title from its golden coloration which is definitely variable.

To a sure extent, they’re able to change their coloration and if one watches them they are typically a darker coloration when swimming decreases within the substrate close to the underside.

When larger up within the substrate the physique and fins are a ravishing golden yellow coloration.

The attention has two blue traces by means of it and the lips are sometimes blue with a purple line alongside the underside of the chin.

The dorsal fin is edged in blue. A really enticing fish with a particular slinky swimming type.

The physique is a typical blenny form with an elongated physique with a blunt head.

The dorsal and anal fins are steady and lengthen the size of the physique. Their pectoral fins will not be as distinguished as on many different blennies.

midas blenny

The caudal fin has two brightly colored outer rays and is clearly within the heart giving the impression that they have a full lyretail. On the top, there are a number of small sensory pores.

There’s some sexual dimorphism in that males are bigger measuring as much as 83 mm whereas the females are smaller as much as 53 mm.

Within the male, the primary dorsal fin is enlarged in comparison with the feminine and the rays of the caudal fins are longer than these of the females.


Little or no appears identified of the mating habits however it appears attainable that the males take care of the eggs after mating has taken place.

Midas blenny In the Aquirium

Certainly, Ecsenius species can do effectively in residence aquaria offered the correct precautions are taken earlier than their introduction into the aquarium.

The Midas blenny could swimsuit some aquariums, as a result, if they spend time swimming within the water column, they will make a colorful addition to one tank. They could decide on some invertebrate’s and one must be very cautious that they don’t seem to be bullied by bigger fish.

Though many species may be thought-about good reef aquarium fish, different species and even different people of “secure” species could start to nip at clam mantles, LPS polyps, or to scrape SPS tissue.

It has been hypothesized that they’re able to use the symbiotic algae that reside inside these tissues. Very similar to dwarf angelfish are “hit-n-miss” for reef aquarium suitability, so are Ecsenius blennies.

Be forewarned – it isn’t straightforward to take away these small fish as soon as they’re within the aquarium.

Probably the most suitable choice is eradicating the complete rock wherein the blenny has determined to cover out.

As soon as excessive and dry they tend to leap away from the rock. If you’re not cautious they may land again in your aquarium.

With massive people stretching the measuring tape to an entire ten centimeters, and with the tendency of those fish to not roam nice distances, they make excellent additions to smaller aquariums.

A single specimen will usually do effectively in aquariums of 30 gallons or bigger.

In the event you want to discover a male/feminine pair, make sure to rigorously use the traits laid out right here to discern sexes, and supply, at least, a 75-gallon aquarium in your pair. If two males are added to the identical aquarium, it’s doubtless one will perish.

Mixing species isn’t really helpful as a result of, as soon as once more, they may usually not coexist and the weaker of the 2 can be eradicated.

Though Ecsenius species will not be aggressive within the wild, small gobies could also be in danger from them if stored in the identical aquarium.

The danger escalates if this combo is positioned right into a smaller aquarium.

Ecsenius species will defend their small patch of reef, and defenseless gobies can be unable to flee their aggression.

Barring massive or aggressive predators, Ecsenius can adapt to an aquarium with the most different fish.

Massive however non-predatory fish comparable to surgeonfish, fairy wrasses, and angelfish will largely ignore these blennies.

As may be assumed for many small fish, putting Ecsenius with Groupers, Scorpionfish, or different predators is unwise and will definitely finish with a meal for the predator.

Though these comb-toothed blennies will not be discovered within the wild without lush coral gardens around them, they appear to adapt to aquariums without corals without stressing out.

This may occasionally, in reality, be the most suitable choice, because it eliminates the considerations of mantle nibbling and coral polyp feeding.

One of the many largest considerations, nonetheless, is offering enough hiding areas. With or without coral, many small crevices and look-outs must be offered.

These can be crucial, particularly upon first introducing the blenny to the aquarium. As soon as settled in, the fish will presumably spend a majority of its time sitting on ledges or on the sand in plain view.

Midas blenny Tankmates

As soon as the tankmates and rockwork are beneath management, the selection of meals must be thought-about.

Many of those species are herbivorous with a strict weight-reduction plan of microalgae.

If you’re selecting a species that depends on algae for a big portion of its weight-reduction plan, preparations must be made to make sure microalgae are available for it to eat within the aquarium. The top-of-the-line location for this to happen is the again glass.

By merely by no means cleansing the again glass, most aquariums will readily develop movie algae.

By permitting microalgae to develop on viewable panes of glass the aquarist will get the chance to witness the kiss marks these blennies go away on the glass once they scrape or comb the algae from it.

Hopefully, as time permits the fish to regulate aquarium life it would grow to be accustomed to consuming algae from pellets, flakes, or dried strips generally known as “nori.”

In fact, the bigger the collection of algae supplied, the more healthy the fish can be.

Though some blennies could eat massive quantities of undesirable hair algae, it’s unrealistic to imagine that an Ecsenius species will make any form of a dent in a wholesome crop.

Actually, it’s fairly attainable the person won’t eat any hair algae.

A single Ecsenius species, E. midas, isn’t a strict herbivore and can really desire to eat zooplankton.

For these people, mysid shrimp must be thought-about together with enriched brine shrimp, flake and pellets, or any meals designed for smaller carnivorous fish.

These similar fish will, nonetheless, respect the occasional vegetable of their weight-reduction plan, so be certain to not starve them of their veggies solely.
