What Snails To Add?

[Zante]

I would like to add some snails to my discus tank, but I'm not sure what species would survive in the low mineral water at 30 degrees Celsius without melting. Any ideas?

Possibly from the amazon basin, I'd like to keep the tank an amazon biotope.

i think you may get a better response in the Invertebrates, Amphibians & Aquatic Reptiles Forum. would you like me to move it over for you?

Please. I had a quick look but couldn't spot it, or I would have posted it there.
