Hello I have 3 fire bellied toads in a 10 gallon tank.

I am looking to upgrade them into a bigger tank, and I was thinking of adding some lighting and
a filter. I heard the fire bellies need a basking spot in their tanks, but others say that they don't.
I know that maybe they should have some light but not a basking spot. I heard the fire bellies really
like the swamp glo lights that are blue lights and you would normally turn it on at night.

Also, with the filter, what type of filter would you recommend?

And If I were to upgrade their tank, what size would comfortably fit 3 full grown toads?

and I was also wondering if it is okay to put rocks and sticks from outside in their tank.

Thanks!!!
