Keeping and breeding of the coral catshark (Atelomycterus marmoratus) at the Aquarium of the Cologne Zoo

Coral catsharks (Atelomycterus marmoratus) are kept at the Aquarium of Cologne Zoo in a public exhibit tank measuring 300 x 160 x 110 cm (length x width x water height) with a water volume of ca. 5000 l. The 1.3 adults have been producing fertilized eggs since early 2010. Deposited eggs are longish-oval in shape, with a length of about 10 cm. Juveniles hatched in our rearing tanks (measuring 100-210 x 45-80 x 30-50 cm, with 280-430 l water volume) after periods of 4-6 months. The freshly hatched coral catsharks measured from 10-13 cm in total length. After 3 months, each juvenile had grown about 4-5 cm in length and the distinct, bright color pattern of the juveniles had faded towards the more subtle adult colour pattern. The keeping and breeding of coral catsharks can be classified as uncomplicated, given that sufficient swimming space and hiding places are provided. So far, 14 juvenile coral catsharks have been successfully reared at the Cologne Zoo Aquarium and are now available for breeding projects.
