Mine are in a 10 gallon tank with paper towels lining it (change daily,) food bowls, a water dish (change daily,) and a couple of faux leaves hanging from the screen top. Makes it easy to see exactly how much they've eaten and pooped. Plus, of something ends up being wrong, a fungal infection, parasites, etc, you do not have to rip apart and entire decorated viv to disinfect.
Good catch on the feet, Carlos, I didn't notice that. Bugarte, if you look at the picture you posted, 2 of the feet have red spots on them.
