Hi there! Very new frog owner here with green tree frogs (or that's what I hope they are) and their around 4-5months old and very cute. I have no clue on gender but I do presume the brighter green one Is female and the smaller one is male

On to my main question- is the darker one ok and is it something to be wary of? He's been like this for ages and I do see him (or her still not sure) changing to be a little brighter. The bigger brighter one on the other hand stays that bright green but rarely does have a darker tint to her. Again I'm still very new to keeping frogs and I live around NSW. If anyone has any tips for keeping frogs or reasons to the colour it'd help alot.

Thank you all!
