Purple tang reef compatibility check
Zebrasoma xanthurum
Purple tang (Zebrasoma xanthurum) is an intermediate-level tang that needs at least 100 gallons. It is listed as reef safe; can be very territorial, especially with other tangs. Temperament is aggressive and adults reach about 8 inches. ReefCrafter schedules it as middle-stage livestock, with no tank-age gate beyond a finished cycle.
Beautiful large-system fish that should be planned late and with aggression margin.
Who it is for
Good fit for
- ✓ Tanks of 100+ gallons at the animal's adult size.
- ✓ Newly cycled tanks with a compatible stocking list.
- ✓ Reef tanks with corals and invertebrates.
Not a fit for
- ✕ Tanks under 100 gallons, even while it is small.
- ✕ Keepers without some reef experience and stable parameters.
- ✕ Peaceful community tanks with small, timid fish.
- ✕ Can be very territorial, especially with other tangs.
Compatibility warnings
- Can be very territorial, especially with other tangs.
- 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 100 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.
- Professionals should model aggression by territory and introduction order, not only by care level.
Tank fit and maturity gate
ReefCrafter uses 100 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.
