Purple Mask Angel - Sumireyakko venustus

The Purple Mask Angel (Sumireyakko venustus, also known as the Venustus Angel) is a beautiful and uncommon pygmy angel. This species has a blue-purple head and upper body and a yellow lower half with a yellow triangular marking behind the head. It is similar in behavior and care to the pygmy angels, but is found in deeper water and may not feed right away when it is introduced. Sumireyakko is a new genus and classification; this fish is still known as Centropyge venusta in many references.

The smaller angelfish and "pygmy angelfish" available in the aquarium trade include those from the genera Apolemichthys, Centropyge, Chaetodontoplus, Genicanthus, and a few others. Of these, Apolemichthys and Chaetodontoplus are generally the largest. Centropyge is the largest group and some fish have been separated into new species and genera in recent years.

Suitable tankmates for most of these angels would be community fish like tangs, clownfish, damsels, gobies, blennies, butterflies and similar fish. More shy and passive angels can be kept with smaller, more docile tankmates. Angels should not be kept with other angels in the home aquarium to avoid territorial conflicts. Occasionally, two angels may tolerate one another in a very large aquarium if they have very different coloration and appearance, but is not typical. All angels have cheekspines at the edge of their gill cover and in the dorsal fin; use caution when handling and avoid using a net that they may become stuck or tangled in.

The diet of angels generally consists of meaty foods and algae. They can be fed a variety of frozen items like formulas, mysis shrimp, brine shrimp, scallops and others, as well as pellets, flakes, algae sheets and other foods. Many can be kept successfully in a reef, but use caution with any angels in a reef system, especially with polyps and SPS corals; some have been known to nip at the occasionally polyp, coral or clam mantle but not to the extent of the larger angel species. Genicanthus angelfish are generally planktivores and are not usually a large risk to corals.
