Your frilled needs to be beefed up a litle. As for your golden greek, I would recomend when you can to swich the substrate you have with a mix of 2 parts of play sand with one part of peat, and the woule substrate being kept practicly dry, this guys dont like moist one bit. By the way what are you feeding it? Golden greeks are hardy once established by they tend to be on the delicate side and can be very picky eaters.
