I dust the crickets with calcium and also feed them a few flakes of fish food for protein. I used to use a couple of drops of reptisafe in his water but switched to the calcium duster instead which is about the time when this started happening. I am importing the photo now but a description-he has been lying on the bottom of the cage using only his arms to prop himself on the screen occasionally, one of his legs was almost completely immoble now it seems he can barely use either of them and are arched giving me the idea he has MBD. although his color is still a good shade of green and even bright green when he sleeps, now there is an arch in his spine that almost looks like he is deflating. I cant stand seeing him like this Im heart broken and need to get him professional care.
