Who it is for

Good fit for

  • ✓ Tanks of 10+ gallons at the animal's adult size.
  • ✓ Beginners following a slow, planned stocking order.
  • ✓ Reef tanks with corals and invertebrates.

Not a fit for

  • ✕ Tanks under 10 gallons, even while it is small.
  • ✕ New tanks; wait until the system is about 1+ month old.
  • ✕ Needs a sandbed and some available food.

Compatibility warnings

  • Needs a sandbed and some available food.
  • 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 10 gallon minimum as an adult-planning floor; display length, aquascape, and existing tankmates can raise that floor.
  • Hold this entry until the system has at least 1 month of maturity or equivalent stability evidence.
  • Invert plans should account for copper exposure, acclimation sensitivity, predation risk, and whether the tank can actually feed the animal.
