Compatibility warnings

Large specimens can become opportunistic; avoid green brittle stars for small fish.
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.

ReefCrafter uses 50 gallons as the planning floor for adult size, swimming room, nutrient load, and aggression margin.
