Overview

The body of the Dwarf Sea Hare is a combination of speckles and patterns. The location of its rhinophores (organ used to smell) and its oral tentacles make it look a bit like a rabbit, hence its common name.

If it becomes startled, it may release a purple dye to repel attacking fish. In the home aquarium, the Sea Hare will need a good chemical filter system to quickly remove this toxic dye before it causes problems.

In the wild, it is usually found in shallow areas of seagrasses and coral rubble, preferring the shaded areas. Cover from the lights in the aquarium should be provided. It requires a large area in which to move. It prefers an aquarium with live rock and open sandy areas so that it can graze on algae, eating any Caulerpa in the tank. It is sensitive to high levels of copper-based medications and will not tolerate bad water conditions (high nitrates).

If regular feedings of Caulerpa are not possible, it will need a supplemented diet of parboiled lettuce and dried kelp.

Approximate Purchase Size: 2" to 6"

Caution: This species secretes or releases toxins when stressed or injured that may kill fish in the aquarium. LiveAquaria.com cannot accept responsibility for any loss that may occur should this animal poison the aquarium.

I received a beautiful specimen! It is white with red and brown "racing strips" and what looks like three feathers hanging off its back. Really neat to watch!
