Tank planning

Specimen compatibility

Choose a fish to see how it might share an aquarium with the others on this page. Many of these are large predators, so adult size matters more than size at purchase.

Golden rule · 1

The Tank Size Rule

Do not attempt a multi-monster tank in anything less than 300 to 500+ gallons (minimum 8 feet in length). These fish grow between 2 to 3 feet long and require massive water volume to dilute metabolic waste and diffuse aggression.

Golden rule · 2

The “Mouth Size” Constraint

Ensure every single fish added to the tank is physically too large to fit into the mouth of its tank mates.

Plan around adult size, generous swimming space, and predatory behavior—not the size of a juvenile.
