My William's Blue Dwarf Geckos are getting FAT.....

[justanotherfroginthepond]

....off the CGD!  I'm wondering if I should feed a day gecko diet vs. the CGD as it seems like it should have less protein in it.  My mourning geckos eat the CGD, too, but they look perfect.  Only the blues seem to be packing it on!  Or just skip a few feedings per week?  Any ideas?
