They look like map turtles.

I have read some articles on compact fluorescents being potentially blinding, but have used them successfully for years with my bearded dragons, turtles, and tortoises. I do agree however on the size of the tank. Looks like they're in a 20 gallon long? An upgrade will be needed soon.
