My fiance and I are the excited parents of two baby beardies, but we are worried about the one we believe to be male - he is much smaller than the believe-to-be-female, almost half her weight. He is very similar in length, but she is much heavier. They are about 3 months old, both from the same litter (is litter the right word?). They both eat a similar amount (small crickets every day), and we use droppers to give them water every three days. The temperature in the tank is fine and we have UVB and UVA bulbs, but we're worried about the little guy. Does anyone have experience with this?
