Again, I just use the coconut fiber, clean the walls and plastic plants once a week. And clean their water dishes every day. Every month or so I clean everything out of the viv and put them in a holding viv for a few hours. I am just hoping the orange stuff in their water dishes is just the new substrate and not some sort of weird toxic urine because they're sick. They are pooping and eating like normal, and croak all night with each other. So. I am sure they're okay. I just had a scare when I bought the first little guy and he ended up being really sick (protozoa in poop) and luckily I caught it in time to save him. So now I think I am just paranoid! Lol
