Midas Blenny Feeding Guide
The Midas Blenny is primarily a planktivore — unlike most blennies, which graze algae from rockwork surfaces, the Midas feeds on zooplankton in the water column. This makes it easier to feed than many blennies and more competitive at feeding time in a community tank.
What Midas Blennies Eat
- Frozen mysis shrimp: The most reliable and nutritious staple. Midas Blennies accept mysis readily and will actively intercept it in the water column.
- Frozen brine shrimp: Accepted readily. Enriched brine shrimp is preferable to plain as a supplement.
- Small carnivore or omnivore pellets: Accepted by most individuals. Slow-sinking or neutrally buoyant pellets work well for a mid-water feeder.
- Copepods and amphipods: Will actively hunt pods in a tank with a healthy population.
Feeding Behavior
Unlike the Tailspot Blenny, which spends much of its time grazing surfaces, the Midas Blenny actively swims into the water column to intercept food during feeding. It is a more assertive feeder than most blennies and generally has no trouble competing in a community tank. In tanks with very fast or aggressive feeders, monitor to ensure it is getting adequate food, but this is rarely a problem.
Feeding Frequency
Feed once or twice daily. Offer small amounts the fish will consume within a few minutes. The Midas Blenny has a relatively small mouth for its body size — ensure food items are appropriately sized. Whole large mysis pieces are fine; very large krill chunks may need to be broken up.
Algae Grazing
The Midas Blenny is not a meaningful algae grazer. Unlike the Tailspot Blenny or lawnmower blenny, it does not graze film algae from rockwork or glass. Do not rely on a Midas Blenny for algae control — it will not provide it.

New Fish and Feeding
Newly introduced Midas Blennies may be reluctant to feed for several days while acclimating. Continue offering food near their preferred perch. Most begin feeding actively within a week of introduction once settled.
