Adspersus tend to look more "neon" or bright green when juveniles, not always but usually, and sometimes have pointier mouths.... then the green gets more dull later on as time goes by and it grows. Edulis doesn't change much. I have both. I've had my edulis for about 8 years and I love him soooooooooooooo, soooooooooooooo much. Originally, we all thought he was an adpersus too(I was new to the species then), but I kept him anyway and I am so glad I did. Taking care of him has had such a healing effect on me. The adspersus is WAY more expensive to take car of. They can eat all day every day, 50 large crickets at a time plus worms etc, then still want more. Daily. The edulis only ate a lot when it was young, unassisted, then had to be assisted later in life and only eats 1 worm a day now, to every other day. Sometimes he's very fussy (the longest was about 2 weeks), and I will have to give him a honey bath to make him want food. He's such a cool frog though, you will love him! Edulis is more active when younger, later on they tend to sit around and bury their butts in the mud and don't do much but they're so cute. Keep them misted, they LOVE fresh soil....mine croaks and squaks for hours every soil change, put them in the pool once in a while if they're being lazy (you may have to remove them from the pool too haha). They definitely need babysitting later in life but it's worthwhile. I just joined so I am unsure how to post pics atm, but you can email or message me. I have so many pics and videos.
