Hi first time toad keeper here - long time fish and reptile keeper. I am setting up my fire belly toad tank and I was wondering if I can keep them with fiddler or red clawed crabs?

Here is a pic of my set-up so far



I want to add more green with more plants and moss.

I have done a lot of reading about FBT and I am confused about temperature. Do they need a basking light and a heater for the water? I live in Ohio so my room temps vary from mid 60's in winter to mid 70's in summer.

I welcome any comments on my set-up for far..

Thanks!
