Are fountains safe/good for African Fat Tailed Geckos?

I went to the reptile store recently and the worker managed to persuade me to get an AFT (African fat tailed) gecko, she explained to me that AFT’s need more humidity than a Leo gecko does, and so would a fountain be suitable for an AFT gecko? From what i know their unsafe for Leos so are AFTs different?
