Nice pics mate! Are the P. platurus and O. lesueurii wild animals?
I know a real nice spot around here that has alot of P. platurus. I've found that the regenerated tails are often alot bigger than the original ones. Also the wild broad tails often have many bright, almost fluorescent orange mites living on them. Which as far as i know, are not parastic, but live off the dead skin on the animals - still creepy looking though!
