great looking post but I do have one question does the sipper piece prevern you from removing the tub completly ?? looking at I I be afaird i end up ripping the piece off and possible end up with some drowned rodents.( it would happen with my luck) that why I liked my glass stnaks or even consider finding those lab tubs( sicne i don't know what they are called) that has the clear tub and the wirre tops I can just set them on a shelf unit and pull them out ot do maintanc every day. I love the rack design since it takes up a lot less room than my current 4-5 tanks of rodents.
