Hey everyone, I just got Froggy a week ago. He is a frog eyed gecko, a wonder gecko. Not one of the giant ones. I would really like to add at least one more wonder gecko into the tank in the next couple weeks. I have a 20L cage. I know that I cannot have two males and so I need to figure out if Froggy is a boy or girl. I have done some research and I believe he is a boy but I want to be sure. So two questions. Boy or girl? And how many geckos can be housed comfortable in a 20L tank? Any feedback is appreciated!
