shrivel-y tail on fattail gecko

[Ducksarefun]

Hi,

I am new to lizards so I hope my question isn't toooo basic...

I saw a fattail gecko at the petstore last night and his tail wasn't fat at all. In fact it looked more like a baloon that has lost all of its air. I questioned the guy about it (because I was thinking it was malnourished) and he said "maybe he lost the tail and it's growing back". Also, he was moving more slowly than I would expect. What do you think? Could the guy have been right?

no he wasnt right. if a tail is growing back it wouldnt grow back looking like a ballon with no air. sounds like the poor thing is malnourished like you thought. could be dehydrated.
