How to Care for Midas Blenny

written by Dave Burr

Behavior: The Midas Blenny is a dazzling reef safe fish that will spend plenty of time in full view as it swims around the aquarium looking for bits of food. It is generally very peaceful but may chase off small planktivores such as Firefish and small Anthias. The Midas Blenny does not eat much in the way of algae and will often get along well with algae eating Blennies.

Feeding: Offer the Midas Blenny mysis shrimp, finely chopped meaty foods, and frozen or dried algae preparations.

Soaking all fish food (even algae) with vitamins will help keep your Midas Blenny healthier and make them less susceptible to disease. We recommend soaking food in garlic as well when adding new fish and whenever your notice ich or other disease in the aquarium. Garlic will help repel external parasites and will boost the fishes immunity.

Feeding Tips: Remember to feed slowly. Leftover food will cause nitrates and phosphates to rise. If you see food falling to the sand bed and into the rocks, you should feed slower and give the Midas Blenny a chance to eat before adding a little more. Using a turkey baster allows you to target food to different fish. For example you can feed the aggressive fish on one side of the tank and then squirt a little bit on the other side for the less aggressive fish. This way all the fish get a chance to eat enough.

Maximum Length: 6"
Care Level: Easy
Family: Blenniidae
Reef Compatibility: Yes
Minimum Aquarium Size: 30 gal.
Range: Fiji, Indonesia, Africa
Diet: Omnivore
Water Conditions: 75-80° F; sg 1.024-1.026 (1.025 is ideal); pH 8.1-8.4 Ca 420-440 ppm, Alk 8-9.5 dKH, Mg 1260-1350, Nitrates <10ppm, Phosphates, < .10ppm

Water Chemistry: Maintaining Ammonia at 0 ppm, Nitrites at 0 ppm, and Nitrates below 10ppm will help to keep your Midas Blenny happy and healthy. We recommend doing a water change soon after Nitrates rise above 10 ppm. Maintaining proper calcium (420-440 ppm), alkalinity (8-9.5 dkh - run it 7-8 if you are carbon dosing), and magnesium levels (1260-1350 ppm) will help to keep pH stable in the 8.1-8.4 range. We recommend a specific gravity of 1.024-1.026 with 1.025 being ideal for fish. Temperature should remain stable as well and should stay within a 2 degree range.
