So i created a new terrarium about a month ago, iv had these 3 fire bellys for about 2 months. My last set up they had alot of water to roam, and this new set up is in a 18x18x18 exo terra tank and its better, semi planted tank with drift wood that they love.

Well with this new tank they dont go into the water at all but they stay moist of course. my last set up they were in the water alot. Its pretty much 60/40 Land water.

Is this a problem? Its been about a month in the new tank.

Also there is a marbled salamander in the tank that i got from a friend hes been in the tank as long as the fire bellys they get along well and cuddle in the same spot under the drift wood
He thinks hes a fire belly
Is it bad to keep him in here?
Thanks
