Compatibility warnings
- Escape artist: a tight-fitting lid.
- Eats shrimp and crabs; snails and corals are safe.
- Grows to two feet; build rockwork it cannot topple.
- 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 50 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 3 months of maturity or equivalent stability evidence.
- Professionals should model aggression by territory and introduction order, not only by care level.
