Okay...I'm taking it that the HUGE logs I find in the water dish is their poop. Couldn't someone have warned me.it looks like something my cat did. YIKES! The 5x8 trays of coco fibre are working great. While their sitting in the water dish I just swap out with a fresh tray of soil. They are both still very active at night so I think I'm going to ask Santa for a bigger tank for x-mas. I'm thinking of a 40 gal breeder and put a divider down the middle that way I can stay with one row of lights. Do you think that would be a good size even for them as adults? Theyll top out at two or three inches. Right now they bump into the glass way too much.
