Planning your aquarium

The library starting point is 30+ US gallons. Plan for the approximate 5-inch adult size and the species' normal activity, not just its current shop size.

The minimum group count is not a compatibility recommendation; assess temperament, sex, territory, and tankmates.

Mixed-species aquariums may need substantially more space. Tank length, adult behavior, filtration, and hiding spaces all matter.

Tank setup and behavior

  • Maintain stable, species-appropriate water and provide a mix of cover and swimming room.

Compatibility

The current rule-based checker does not list a dedicated pairing warning for this species. That does not mean every pairing is safe; review temperament, adult size, diet, habitat and water requirements.
