Planning your aquarium

The library starting point is 15+ US gallons. Plan for the approximate 2.5-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

  • Secure the lid and protect gaps around equipment and cables.
  • Break up sightlines with plants or hardscape to create distinct territories.

Use appropriately sized, complete staple foods and rotate suitable foods for variety. Feed modest portions and remove uneaten food.

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.
