I just picked up 2 sets of 1.2 ASF's to give breeding a go. They are in 10 gallon aquariums right now. Due to my rapidly shrinking available space, I would like to set up a typical rack system with tubs, gravity fed water and feed lab blocks on top of the screen.
I have seen racks that use kitty litter pans, mortar tubs and sterilite containers. None of these seem as good as glass aquariums. I have limited space so having a bunch of aquariums is out of the question. I have seen people mention those metal steam table pans, but I have never heard of anyone actually using them or building a rack for them. I think this is what I am going to use.
I plan on making a 6 shelf rack. 2 bins for the breeders, 2 bins for the weaned rats, and 2 bins for grow ups. My question is what size pan to use for each of these? I can get the pans in 4" and 6" deep. The 6" seems like it would be too deep for the weaned rats to reach the food and water at the top of the tub. the 4" pans seem very shallow. I am only 3 days into this project and would like to here from others that have experience with raising ASF's in racks. What depth should I go with?
