I'm looking at increasing my production. Currently, I'm using medium lab cages (18" deep and 12" wide - 216 square inches). I'm looking at two different rack systems. One is 9.5" wide and 21.5" deep (about 11.75 square inches smaller than current). The advantage of this rack is that it has 50 tubs. I'm a little concerned that it is not enough floor space for a treo (sometimes I do quads - 3 females to 1 male). The other rack system only has 32 tubs but the floor space is 13" wide and 27" deep (351 square inches). The extra 18 tubs of the 50 tub rack would sure be nice. For comparison, I looked up a ten gallon fish tank and it is 10 inches by 20 inches (200 square inches), which is smaller than what I'm currently using and less than the 50 tub setup. In other words, the smaller tubs would still be about 4 1/2 square inches larger than a 10 gal fish tank.
Anyone keeping treos in space similar to 9 1/2 inches by 21 1/2 inches? How about ten gallon tanks? Do you have problems with over crowding in a ten gallon when litters are near weaned?
