I'm new here and new to fire bellies. I just got 2 a couple days ago and have them in a 10 gallon that is half water/half substrate. The substrate I'm using is about a 60/40 mix of coir and organic topsoil. The substrate was damp when I put it in and I mist it very lightly daily. My question is that one of the toads is very active and spends his day swimming and hanging out and the other was active for the first day but now has hidden under some moss in the tank and I haven't seen him since. This was yesterday evening and I'm not sure if I should be worried. Is he just hiding because he's in a new place or should I dig him out and make sure he's ok? I know he's alive, I see the moss move on occasion but I don't see him at all.
