I personally use laboratory grade breeding tubs. I run 1.2 and have never had any canabolism and ZERO escapees.

My tubs average 15-25 babies about every month-month and 1/2 and all is well.

The lid doubles as a feeder and bottle holder so you don't have to worry about food hoppers, the bottles (plastic) aren't chewed through and you can even use watering systems with the tubs I have. They're lightweight and NOT glass so you don't have to worry about working with bulky 10 gallon+ tanks. They're also easy to clean!

For asf rats, I'll never use anything else again. I'm having a lot of success with these!

Just remember if you decide to get them, don't use Big Apple's tubs!!!! I tried them with MICE and the MICE chewed them. ASF rats would have devoured them in a day!
