Hello
From my knowledge, B. schneideri has never been bred in captivity - even in Europe oder the USA. I have had bred peringueyi twice, and one have had 3 babies from an pregnant illegal exported female from Swakopmund Namibia, which ended at my place and gave birth to 2.1 healthy little cuties
Unfortunately at the moment I do not have a good breeding group any longer - would love to bred them again because with CB animals we can avoid that further speciemens will be illegaly exported just for the trade and pet marked. But problem is, WC animals you can get here easely for 200 Euro each, for CB I was asking 400 Euro per animal anno 2005 - so laymen have always prefer the much cheaper WC animals. Unfortunately they all die within some weeks, when they arrive in wrong an inexperienced hands. That's also the reason why many are thinking that peringueyi is not doin well in captivity......I have a single male from my CB 2005 at home, and he's doing fine and growing like weeds.
With schneideri it is different, from my experiences females are often doing great for years, but males die within weeks or months after arrival. Usually females also do better accept mice as food, males usually refuse - which means you have to feed lizzards :-/
They are very very interesting animals, and I love schneideri soo much, but will never try to work with them again - it's a shame to work with illegaly imported animals, from which is known that they will die with greatest possible guarantee !!
Will more concentrate on peringueyi, caudalis, cornuta and atropos in the future and try to bred them regularly - thinks that's the best way.
Cheers
Marco
