Swordtail
Active livebearer; males can chase each other.
Planning your aquarium
The library starting point is 20+ US gallons. Plan for the approximate 5-inch adult size and the species' normal activity, not just its current shop size.
The library suggests a group of at least 3. Count every individual when estimating stocking and swimming room.
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.
Leave a long open area for active swimming, with plants that give chased fish cover.
Active livebearer; males can chase each other.
Food and feeding
Food options: Tropical flakes, Small pellets, Blanched vegetables.
Use appropriately sized, complete staple foods and rotate suitable foods for variety. Feed modest portions and remove uneaten food.
Additional care caution
Males can pursue one another, and mixed-sex groups reproduce readily.
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.
