Sand: Is it a safe substrate?

[Poly]

Yes exactly! I figured because they come for a sandy area, it wouldn't be a problem. When I used soil for substrate, they didn't seem very happy, so I added a small sandy patch, then they would burry themselves in that patch, and pretty much ignore the rest of the tank, so when I changed the substrate to all sand they seemed MUCH happier, and moved around much more! To be honest, as for the "sand sticking to their eyes" concern, I had never seen this before, but I just wanted to clarify whether it may or may not be something I need to change.

Oh, and it is jusr regular brown sand, much like beach sand.

I think there fine. When you do a substrate change maybe go to play sand (100% silica sand) from any hardwear store. Its like $5-10 for 50lbs and its clean of any foreign material, just give it a good rinse to get rid of any dust. To me your just mimicing there natural habitat which is what keeping frogs/toads- any animal is all about.
