Compatibility warnings

  • Can bulldoze frags and carry objects.
  • 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.
