It's a little bit confusing here. First the main reason why i originally skipped the species list here. All the terrariums at the room with the native herps are designed in a way that one merge into the next one. And with the signage, i wasn't always 100% sure to which of the single exhibits the animal exactly belongs. Furthermore a bunch of species is kept at more than one of the terrariums.
So to answer the question. The left part of the exhibits with the two glasses on top of each other has crested newts and European tree frogs. The glas between the main exhibit is barely visible. At the main tank there are unsigned fish, European pond turtles, Marsh frogs and probably dice snakes. The snakes were definitely signed here, but i haven't seen them at this terrarium, but at another one.
