I just purchased 2 waxys within the last 10 days. My first one is thriving well (from the git-go), eating tons of crickets, not hiding alot & is a bright lime green color. I first purchase him & decided I wanted to get another so 3 days later I got the second. I have had him now for a week and he stays hidden most of the time (even at night with the red bulb on) & is staying a brownish color. He's eating daily small crickets (I hand feed them both with tweezers) but is just not as active as the other. I've seen him in the water bowl a few times so I know he's staying hydrated. All other conditions are as they should be based on the reading I did prior to getting them. Is this anything to worry about or should I give it more time? I have another week before I can't return him & am seriously thinking of getting a different one. BTW they both came from the same place...same tank even. Thanks
