This is not a reef safe crab and will certainly eat other invertebrates and small fish. Decorations and tank equipment must also be protected against its strong claws.

Iodide levels must be properly maintained as this substance is required for healthy moulting.

As with all invertibrates it is sensitive to high nitrate levels and copper-based medications
