6qt for the Enchi Pastel- he's only 150g.
The Champagne and the SuperPastel are in V-18 tubs (18" x 5" x 3.5")... plenty big enough for 600g. I move them to 41qt when they hit 900g- 1000g. The Pastel is 900g and that is her 3rd meal since I moved her a month ago. She refused 1st week in the larger tub.
