I got my info from NERD, Henry Piorun, and Garrick Demeyer. As for my comment on my sd retics not being all that active is from my observations. Yes they do move around at night and sometime during the morning, but mostly during the day no (sorry I should a specified.) About 4 months ago (when they were about 3 feet) I did upgrade them to a CB 70, once I did that I noticed they were more aggressive than usual and went off feed, about 3 weeks and 3 refused meals later I decided to put them back in their old tubs - which was something roughly the size of a 32 qt. tub but with more height. Once I put them back, they started feeding again, and their behavior was back to what it use to be.
As for the tub debate, for Super Dwarf Retics I disagree. Not all tubs are low height. Some have more than enough climbing space for a super dwarf.
PS: sorry for the delayed response, I broke my glasses and I can barely read a thing, had to get help from my cousin to read.
