The Harlequin Bubble Sea Slug, or Cymbal Bubble Sea Slug, may also be referred to as the Harlequin Bubble Nudibranch although it is not a true nudibranch. This very beautiful shelled sea slug is characterized by its bright orange spots and purple markings on a translucent green body. Occasionally, the orange spots or purple markings may be absent but it is still identifiable by its body shape. These slugs are reef safe, and are an excellent addition to a saltwater reef or fish aquarium.
It is typically uncommon, but when found it occurs in large groups in tropical seas. It will do well in an aquarium, if provided with ample room to forage. It prefers an aquarium with live rock so that it can graze on algae. Its diet consists of filamentous algae and unicellular algal film, which it grinds using toothed plates. It can be harmed by pump intakes and drains, so care should be taken to screen these off. It is sensitive to high levels of nitrate and will not tolerate copper-based medications.
Approximate Purchase Size: 1/4" - 3/4"
