They are in a 10 tub rack, 41q Sterilite containers. I am not going with the ceramic at all......I thought of switching but I will just spray extra water in the tub when they shed. My humidity stays consistently between 50-60% with my 8oz disposable plastic bowls. I know Petco, Petsmart, etc. has them but I was just wondering if other places had them for a better price. I saw descent ones at Walmart, Target, and other stores for half the price of pet stores though. Thanks for the reply.
