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.
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 4 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.

This animal should wait until the tank has enough age, food web stability, or parameter history.
