There is also one (excellent) report of Thomas Mutz on captive breeding of Hydromantes (Speleomantes) imperialis, fairly closely related to Bolitoglossa but, unfortunately for most of you, in German. Because this is quite a large forum: how many people actually have healthy groups of Central and South American plethodontids? The only one, more or less regularly imported species into Belgium appears to be B. dofleini, which has experienced a terribly high mortality rate.
