Compatibility warnings
- Drops its crown when stressed; it regrows if the tube is left alone.
- Needs regular fine foods or it slowly starves.
- 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 3 months 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.
