I dont believe the sulfa dip will help. I would raise the water temp to 80F and make sure the air temp in the aquarium is equally as warm, if not warmer.

I am currently in the US Navy, so unfortunetly I have sold off my collection of herps. But over the years have kept many different species of turtles, geckos, lizards, amphibs, and even fish. Looking forward to getting back in the hobby once im out though!
