Caring for the bullseye snakehead

The bullseye snakehead needs at least 396 gal (1,500 L), with a long footprint and a heavy, sealed lid. Confirm it is legal to keep where you live before you take one on.

Keep it at 72 to 82°F (22 to 28°C) and pH 6.5 to 7.5. Feed prawns, fish, earthworms and other meaty foods.

It is predatory, territorial and aggressive, so keep it singly or with very large, robust tank mates only. Breeding it in a tank is hard.
