Who it is for

Good fit for

  • ✓ Tanks of 40+ gallons at the animal's adult size.
  • ✓ Newly cycled tanks with a compatible stocking list.
  • ✓ Reef tanks with corals and invertebrates.
  • ✓ Peaceful community tanks.

Not a fit for

  • ✕ Tanks under 40 gallons, even while it is small.
  • ✕ Keepers without some reef experience and stable parameters.
  • ✕ Needs a tight lid.

Compatibility warnings

  • Needs a tight lid.
  • Can be bullied by aggressive tankmates.
  • Check adult size against the final tank, not the fish or coral at purchase size.
  • Add livestock slowly so the bioload and nutrient export can keep up.
  • Use the planner when this animal changes the tank-size, flow, lighting, or stocking plan.

Professional planning context

  • Use the 40 gallon minimum as an adult-planning floor; display length, aquascape, and existing tankmates can raise that floor.
  • This can be planned early after cycling, but only after quarantine/acclimation logistics and stocking order are settled.
  • Professionals should model aggression by territory and introduction order, not only by care level.
