Many breeders keep adult females in 28qt tubs, it is doable. Just make sure if you feed live that they have space enough to strike and coil.
I have 2 2500g+ females in 28qt with no issue. I also have 2 1500g females as well. Once I have enough to build a rack I may just build a 41qt tub rack, but until then they are doing just fine. I'm even breeding in them and I'm expecting eggs in the next month.
