Update
It turns out they r both female after all. ( well at least 1 of them is a 100%) It's the small darker one. I took on foti advise n got me self a mature male. After seeing this guy, looking back at the other two, I can c a big difference straight away. The hair, the head and the body shape, it really stands out. Anyway, after got the male i put him with the other two which were caving in separate cave at that moment. Next thing I know that night the male trap the small female in a cave. 1 and a half day later, he's fanning his clutch of eggs :woohoo: which make me think, either I'm lucky to get two female or the seller stuff him self up by thinking he sold me a breeding pair
. For all that is worth, his lost is my gain. Now the questions has been answered. Thanks for all your opions
