Thannks Notop, yeah I looked up the differences after I posted, I'll have to see if I can get a better look. The frogs are pretty fearless, they don't really move until you're within a few inches of touching them. The EPT is pretty big...I did have a northern redbelly a while back that was about twice her size. Looked like someone was dropping a bowling ball into the water when she dove off the basking area.
