Behavior & Husbandry

Lawnmower Blennies spend nearly all their time grazing algae from rockwork and glass. They are constant workers and provide natural algae control in reef systems.

They may become territorial toward similar species, especially in smaller tanks.


Feeding & Diet

Primarily herbivorous and constant grazer.

What We Feed at Lush Corals:

  • Algae-based foods
  • Pellets
  • Frozen foods

In Your Aquarium:

  • Nori
  • Herbivore pellets
  • Natural algae growth
  • Supplemental feeding as needed

A tank with established algae growth is highly beneficial.


Compatibility Notes

Works well with:

  • Clownfish
  • Gobies
  • Wrasses

Avoid housing with similar blennies in smaller systems.


Lush Corals Quarantine & Conditioning Process

This fish has completed our full quarantine and conditioning protocol (minimum 2 weeks) prior to being made available.

During this process, each fish is:

  • Carefully observed and stabilized
  • Proactively treated and monitored
  • Conditioned onto prepared foods
  • Verified to be actively eating and thriving

This extended process significantly reduces stress and increases long-term success, ensuring you receive a fish that is healthy, stable, and truly ready for your reef.

We don’t rush fish to market—every quarantined fish we offer has been given the time it needs to succeed in your aquarium.
