This just appeared in Turtles tank where he usually goes to the bathroom. I was just wondering if it is possibly a bladder stone. It has a very mineral'y texture to it. And it's pretty solid,
Looks like a rock he ate while outside. Is that a possibility?
Supplementing with MinerAll from Sticky Tongue Farms, seems to curb this behavior. I see it most frequently in tortoises that are fed mostly grocery store greens.
