Hello everyone,

I am currently building a paludarium in an exo terra (90cm tall x 60cm wide x 45cm deep) and the land area will tank up just under half of the aquarium section at the bottom. I am hoping to keep a mountain horned dragon in here as there will be plenty of space for him higher up and since they are arboreal i feel like the land area may be large enough.

Does anyone have any knowledge as to whether the mountain horned is likely to kill any tropical fish i put in the aquarium area which will be roughly 10 gallons with tetras and one apistogramma?

Do you think an apistogramma and tetras would get on okay?

I am open to suggestions on inhabitants of both the land and water areas but i would like one large lizard instead of lots of small anoles for example.

Any help would be greatly appreciated!

No idea about lizards and fish but the apisto should get on fine with tetras. Sounds like an interesting project.
A 10 gallon tank is too small, most tetras need to be in a shoal of at least 6 or more of their own kind and have room to swim.
If you could make the water area closer to 20g that would work much better :)
