Midas Blenny



The Midas Blenny is an ideal option for an aquarium with a reef. It's a stunning deep golden-yellow color with a blue-blue shadow under the chin and clear blue-rimmed eyes. While swimming, the movement they make is very eel-like. The blenny would prefer having a minimum tank that is 30 gallons or greater with plenty of rocks to rest. Sometimes the Midas Blenny can cause trouble to small planktivores and has been reported to attack gobies and fish. Tanks that are larger are more beneficial since some of the Midas's aggression traits appear to be related to a confined tank environment.   Contrary to other blennies, this saltwater aquarium fish needs a substantial diet that includes small pieces of crustacean flesh Mysis, vitamin-rich brine shrimps, as well as frozen herbivorous dishes of blue-green algae and other algae based foods.   Approximate Purchase Size: Small: 1" to 2"; Medium: 2" to 3"; Large: 3" to 4"; X Large 4" to 6"

General info about Midas Blenny The Midas Blenny is a fantastic fish to put in an aquarium with a reef. It's beautiful deep golden yellow with a blue shadow under the chin, and bright blue-rimmed eyes. When they swim, the motion it uses is very similar to an eel. This blenny would be happy in an oversized medium or large tank that has plenty of rocks to sit on. Sometimes, the Midas blenny can irritate small planktivores and is recognized for its ability to attack gobies and firefish. The larger tanks are beneficial as many of this blenny species aggressive behaviors appear to be a result of a tight tank.

Helpful Questions From Clients
Frequently Asked Questions
Is hiring a professional necessary to set up a saltwater aquarium?

As a general rule, a larger custom aquarium might require installation by a professional. However, a kit from our online fish store is relatively affordable and beginner friendly. That means you should have no problem setting it up yourself.

Which saltwater aquarium fish should you choose when starting out?

Consider a yellow tang fish. This popular saltwater aquarium fish does a great job of coexisting with other types of fish you’ll find in our online fish store.

How does a saltwater aquarium differ from a freshwater one?

Saltwater aquariums require a bit more maintenance and monitoring than freshwater tanks. Different fish require different levels of salinity, pH tolerances, and temperature requirements. They also require specialized pumps, filters, and other equipment that can handle salt. We can guide you through everything you need to know to set up a healthy, thriving reef tank.

Do fish in a saltwater aquarium swim in a school?

That depends on the species. However, if it’s a fish that swims in a school in the wild, they’ll do the same in an aquarium. Some fish that swim in schools include the green and blue chromis, cardinalfish, and dartfish, for example. When ordering from an online fish store, make sure you do your research on how specific fish species behave to ensure they’ll school (or at least coexist) with your current fish.

Is the effort required to maintain a saltwater aquarium worth it?

Yes! Many aquarists dream of owning thriving saltwater aquariums. You have a tiny piece of the ocean in your home, featuring magical and exotic fish that can only survive in saltwater.
