Hi guys, thanks for the advice. One more question i have, arising from the links you gave me Chris,( though the question is for anyone who can help). "Roo" gives some really excellent advice on preparing a viv for pygmy chams, and among that advice is the fact that a colony of Springtails and one of sowbugs can help break down any unremoved fecal matter and other contaminants. I live in England, ( hey, someone has to!), and I also know nothing about bugs. Does anyone know if we have them or anything which would do a similar job over here? Perhaps small earthworms may suit? Any help would be appreciated, thanks. Jimmy H.
