Who it is for
Good fit for
- ✓ Tanks of 30+ gallons at the animal's adult size.
- ✓ Beginners following a slow, planned stocking order.
- ✓ Newly cycled tanks with a compatible stocking list.
- ✓ Reef tanks with corals and invertebrates.
Not a fit for
- ✕ Tanks under 30 gallons, even while it is small.
- ✕ Multiple adults may fight unless paired.
Compatibility warnings
- Multiple adults may fight unless paired.
- 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 30 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 30 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.
