I have been keeping my initial 2.2 in a large tank, and have a few trios in small tanks, but use tubs as grow out containers. I find the ones that I have been handling from day one are not chewers, so they do OK in tubs, but that the first ones I got are major chewers and need tanks.

The goal though is to build a rack for them in the near future. Just seems like it will make the whole system easier.
