Thanks, all. I agree, they all mature at such different ages, it's crazy. They're like pre- and post-pubescent boys. His clutch mate could eat him. But, i have females that have more color on them than this guy. I suppose I could just wait a month until it becomes more apparent.
My only concern was what the breeder said to me at the time of sale. He told me they had only females left. I told him I had enough females so was looking for a nice male. Next day, he emailed me back and said he found one male mixed in with the females.
Hey, I give you guys who are good at sexing a kudos. I know the concept behind it, but I can't actually do it. I start doubting and second guessing and then they eventually all look the same. One breeder have told me that it's more common to mistake a male as being a female than the other way around.
