Neon goby reef compatibility check
Elacatinus oceanops
Neon goby (Elacatinus oceanops) is a beginner-level goby that needs at least 10 gallons. It is listed as reef safe; small size means it can be outcompeted or harassed. Temperament is peaceful and adults reach about 2 inches. ReefCrafter schedules it as middle-stage livestock, with no tank-age gate beyond a finished cycle.
Small hardy reef-safe goby that suits peaceful nano and community reefs.
Who it is for
Good fit for
- ✓ Tanks of 10+ 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 10 gallons, even while it is small.
- ✕ Small size means it can be outcompeted or harassed.
Compatibility warnings
- Small size means it can be outcompeted or harassed.
- 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 10 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 10 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.
