Frog ID and a question
I have had this frog in portugal on my land for 3 years. I have built him a pond. There is no water nearby so i have no idea where he first came from. He appeared in a bowl of stagnant water.
Is it possible to know if it is a male or female? I call it Mr. Bernard Sanders, but i don't know.
I feel bad because it is alone. Should i relocate him to a bigger body of water or find him a potential partner?
