Spotted Congo Puffers spend most of their time at or near the tank's bottom and enjoy a heavily planted tanks with lots of hiding places and line of sight breaks. Keep this in mind when picking out a tank. Wide and deep tanks are better than tall skinny tanks. The puffers can easily become injured by decor with sharp points or edges and it's best to avoid them in the tank. Although rare, the puffers have been known to jump and a lid is recommended.
432 square inches of tank bottom per adult puffer is recommended.
(example: 48" by 18" tank = 864 square inches of bottom space)
