Compatibility warnings
- Needs live food several times every day.
- Very gentle filtration in a small dedicated tank; no powerheads.
- 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 5 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.
