Now please correct me if I'm wrong but from what I've read and heard it's mostly got to do with their habitat loss. It's like with plecos... when I got into them 8 years ago, many many different species were available, and now some that I have, for example the L260 (Queen Arabesque Pleco) are on a banned list due to habitat loss from existing/planned dam construction, unavailable to import, and breeders that raise them charge to much for pet stores to want to buy them, so they are sold privately for the most part. I have seen some breeders for Surinam Horned Frogs online, prices on average around 40-80 bucks for little ones and I would imagine that price will only go up.
