Did not know that either! Darn i guess i should have done my homework! Will newts be ok?
If they are Fire bellied newts the excrete a toxin too. It totally different from the toxin produced by FBT's. As a rule mixing newts and FBT's is a no no. If you want info on both check this site out http://www.caudata.org/forum/
I may have to set up my Waters edge kit now. I bought both Viquarium kits produced by Tetra two years ago on E-bay and haven't used them yet. No they are not for sale.
