Common name: Randall's Blenny

General information

Randall's Blenny, scientifically known as Ecsenius randalli, is a small, colorful fish that is well-regarded in the reefkeeping community for its personality and algae-eating habits. This species is named after the ichthyologist John E. Randall and is often appreciated for its mimicry abilities, resembling the toxic Meiacanthus blennies as a form of protective Batesian mimicry.

Care

Randall's Blenny is a hardy species that adapts well to life in captivity. It requires an established tank with plenty of live rock for grazing and hiding. This blenny is peaceful and can be kept with a variety of tank mates, but it may show territorial behavior towards other blennies. A varied diet that includes algae and meaty foods will keep it healthy and vibrant.

Reproduction

In the wild, Randall's Blennies are oviparous, with males often guarding and aerating the eggs until they hatch. Breeding them in captivity can be challenging, and a separate breeding tank is recommended for those interested in raising the fry.

Habitat

Randall's Blenny is native to the Red Sea and the Western Indian Ocean. It prefers shallow, coral-rich environments and is often found in close association with branching corals and rubble zones.
