i have 2 juvinile figure 8 puffers and i feed them about 3/4 of a cube of frozen blood worms each day, and then at night they get a snail. I noticed they look quite plump after each feeding so i wanted to make sure it wasnt me feeding them too much...pictures are attached, they are speedy, so the photos are bad, but good enough to give you an idea of their shape. Thanks!
