Thor amboinensis
Sexy shrimp (Thor amboinensis) is a beginner-level shrimp that needs at least 5 gallons. It is reef safe with caution; may irritate some corals; can be eaten by fish. Temperament varies and adults reach about 1 inches. ReefCrafter schedules it as middle-stage livestock, with no tank-age gate beyond a finished cycle.

Who it is for
Good fit for
- ✓ Tanks of 5+ gallons at the animal's adult size.
- ✓ Beginners following a slow, planned stocking order.
- ✓ Newly cycled tanks with a compatible stocking list.
Not a fit for
- ✕ Tanks under 5 gallons, even while it is small.
- ✕ Reefs where the cautions on this page would put existing corals or inverts at risk.
- ✕ May irritate some corals; can be eaten by fish.
Compatibility warnings
- May irritate some corals; can be eaten by 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 5 gallon minimum as an adult-planning floor; display length, aquascape, and existing tankmates can raise that floor.
- This can be planned early after cycling, but only after quarantine/acclimation logistics and stocking order are settled.
- Invert plans should account for copper exposure, acclimation sensitivity, predation risk, and whether the tank can actually feed the animal.
Tank fit and maturity gate
ReefCrafter uses 5 gallons as the planning floor for adult size, swimming room, nutrient load, and aggression margin.
This species can be planned early when the tank is cycled and the rest of the stocking list is compatible.
