Captive breeding frogs
A small, replicated study in 2005–2009 of captive Malayan horned frogs Megophrys nasuta at Cologne Zoo, Germany (Wildenhues et al. 2012) found that frogs bred successfully. Between 50 and 300 larvae hatched/egg batch. The minimum interval between egg laying was about a month. Dry followed by phases of intense water spraying triggered reproduction. Larval development was faster at higher water temperatures and lower densities. Three males and two females obtained from the pet trade were housed in aquariums (145 x 60 x 56 cm) divided into aquatic and terrestrial sections. Larvae were moved to plastic tanks (13 L water). Two–month-old tadpoles were transferred into aquariums (54 x 65 x 30 cm) and metamorphs and juveniles, in groups of 20–30, into tanks (60 x 45 x 30 cm).
