Compatibility warnings

Plan the pair early because a bonded pair can defend a corner.
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.

Tank minimum

20 gallons

ReefCrafter uses 20 gallons as the planning floor for adult size, swimming room, nutrient load, and aggression margin.

Maturity gate

No special delay

This species can be planned early when the tank is cycled and the rest of the stocking list is compatible.
