I am getting ready to set up my first viv in a 10 gal tank. I'm not sure on the substrate, though. I've read that, generally, leaf litter is the substrate that dart frogs encounter in the wild. However, I dont know alot about its use in captivity. Does anyone have any info on this? What type of leaves to use, pros/cons, maintenance, etc? What do you all use for substrate?Thanks alot.
