Species Profile on the Coral Catshark


Common Name: Coral Catshark

Scientific Name: - Genus: Atelomycterus - Species: marmoratus

Alias: Coral Cat, & sometimes misnamed Tiger Shark

Adult Size: - Maximum: about 28"(71 cm) - Average: about 24” (61 cm)

Adult Weight: - Maximum: about 3 lbs (1.36 kg) - Average: about 2.0 lbs (0.9 kg)

Size at birth: about 3.9” (10 cm)

Size & Age at Maturity: about 18-20” (46-51 cm) for males at about 2-3 years old, and about 18-21”(46-53 cm) for females at about 3 years of age.

Lifespan of species: about 15-20 years.

Geographical Distribution: found in the western Pacific, from Japan to the Philippines, Thailand to New Guinea, and Indonesia to Pakistan.

Habitat: A very abundant small warm-temperate to tropical shark - found in tidal areas, sandy slopes & shallow reefs. Has been found in waters as deep as 33ft (10 meters).

Diet: Mostly invertebrates & small fish - like urchins, shrimp, crabs, mollusks (i.e. clams, squid, or octopus), and segmented worms. Will also feed on small fishes.

Water Temperature & Conditions: often considered a tropical water species, the preferred water temperature range is between - 72-84F (22-29 C). However this species can tolerate, in the wild - water temps as high as 90F (32 C). They seem to prefer salinities in the range of 27-35 ppt or about 1.020 -1.026 SG, with a pH of 8.0-8.4

Minimum tank/pond size: while juveniles can be kept in a tank smaller than 180 gallons. A single adult Coral catshark needs a tank of about 6' Long x 3' wide x 2' deep or 270 gallons. For a small breeding group of 2-3 adult sharks a tank of at least - 420 gallons or 8' long x 3.5' wide x 2' deep, is recommended.

Captivity Care: This species does very well in captivity, and feeds rather easily, once acclimated. Although it may take juveniles a while to fully acclimate. The species does will with some live rock decor. Unlike Bamboos & Epaulettes, the Coral Catshark is known for swimming around a tank rather than "walking". This species is rarer than the Brown-banded Bamboo, but still often seen in the trade. But like most bamboos, it often recommended – as a possible choice for those new to shark keeping.

Captivity Breeding: This species has been known to breed in captivity. And has successfully been bred in large ponds by private keepers. Its small adult size makes it an ideal candidate for captivity breeding by private aquarists.

Potential Problems: While parasites & goiters are problems for all sharks. This species tend to be more active than bamboos and eppies – and therefore needs an addition feeding per week to maintain it’s health & weigh

Other Related Species: While the Atelomycterus Catsharks are the only tropical catsharks. While the Genus has 3-4 species in it. Only two are usually known to appear in North American Fish Shop he most commonly found member of its genus – the Coral Catshark, and the Marbled Catshark. The Marbled Catshark (Atelomycterus macleayi) tends to have a duller coloration, with small black spots, instead of the white spots of the Coral. The Marbled also grows only to 24” long.
