They are mostly darts, but they are also breeding a few treefrog species and they have a few newt species as well. When I was there in June they had some marbled newts I think they are hoping to breed. They also had some Cynops and Tylototriton for sale. They are breeding red-eyes, as well as loads of darts. I believe they also breed powder blue reed frogs, but I am not sure of this. Their faculity is quite impressive. Loads of heavliy planted terrariums, a green house, a room just for tadpoles, a room just for fruit flies, and so on.
