well the reason they're in 15 qt is cuz a hide on both ends (even though they're pretty dang small) plus water bowl equals almost no room to move in. i was actually thinking of getting slightly bigger tubs cuz they're always always (at night) trying to escape, even though their temps are normal. yeah the good feeder ate two large pinks last night, and i was thinking of moving to fuzzies, but how old are fuzzies? just as soon as they start growing...well fuzz..then they qualify as fuzzies? and are they normal weights, i mean not underweight or anything? cuz i thought they looked fine, then i saw some pics of actually healthy balls and freaked a little haha
