It all depends on the toad. There are some toads that prefer a more aquatic environment and some that like more terrain . I have talked to other FBT people who said they originally started with a more aquatic environment and there toads never really left the land portion/dock. So they changed it to have a primarily land environment with a small water dish/jacuzzi and their toads were much more happy. Also, as for fogger and humidifers, there are a few reasons for that. If you have a primarily land habitat then you need something to keep them moist, hydrated and humidity level high. Plus, depending on your toad species, some of them come from areas that are quite humid and the humidity and fog are more along the lines of keeping their habitat as natural as possible. I have a fogger and my habitat is primarily aquatic, but they LOVE when the fogger comes on! Before I got the fogger I was using a spray bottle to keep the humidity level up, they LOVED that- it was like standing in the rain for them. They would always come out from where they were hiding to get their shower.Plus, I live in an extremly dry climate, no matter if it is winter or summer. Also, another thing to keep in mind. They are fire-bellied TOADS. Now these toads are perceived more like frogs because they do enjoy water and swimming like frogs but they are still toads and therefor don't want/need to be submerged all the time. Frog Facts - Frogs vs. Toads to show you the difference between frogs and toads. "They are highly aquatic and usually found in slow-moving streams and ponds. When out of water, they stick to the region’s coniferous and broadleaved forests." from Oriental Fire-bellied Toads, Oriental Fire-bellied Toad Pictures, Oriental Fire-bellied Toad Facts - National Geographic. So, it's all a matter of what your toads like and what works with your lifestyle. Everyone is different!Hope this helps!
