After much deliberation, I've decided to seperate my dwarf puffer from her current tank. I've noticed she's been nippy and moody lately. Will a two gallon tank be large enough for her?
A 2 gal should be fine as long as you make sure to do daily water changes. With such a small tank you will get a build up of chemicals in the water a lot quicker and the puffers are very sensitive to chemicals. If you could get a 7.5 or 10 gal it would be better.
