poor thing!!!
i was out of the newt game for a while but was surpirsed to see many warty newts for sale in shops around here.
i was totally set on buying a shanjin this year advertised by a local shop, and now have a s.s teretisirs fire sal but temporally rescued what i believe to be fuzhoung warties in bad health. unfortunealty they were housed with FBTs, FBNs, and taricha g's at the petshop(some were floating dead in the tank). i bought them for $8.99 with open wounds and despite my best efforts didn't live more than a month. the pics you have posted looked like this aniaml was done from day one and i admire your devote to rescue it, best of luck
