Well, my mom was at the pet store and wanted to know if I wanted another White's Tree frog. Of course I jumped at the opportunity. It had been a while since Kisses..my current White's had had a friend(RIP Sprite) Kisses is kind of small though, only about 2.5 to 3 inches..and I've had him/her for about a year and a half now..... Anyway, The frog at the store is bigger..like 4 inches to 4.5 inches and I was just wondering if it was safe to put them together(after the 30 day quarantine of course) Also, any 'sure-fire' way to determine gender between White's? Thanks guys!!
