Kali_Ma, I'm sorry that Rasputin didn't make it. It's hard to lose any crab, but especially so for the ones we make a special investment of hope in. As for Indo care, I've been wondering if Indos don't need to be on the lower end of the humidity spectrum, just as the Straws need to be on the higher end. We know that they don't like baths, and are found further inland than other species generally. This could be why they're doing well in your tank Ally. Do your indos like to keep off the substrate, where it's drier? I seem to recall someone once saying that they kept gravel in a portion of their tank because it stayed drier on the surface and their Indos preferred that part of the tank.
