Bloodfin Tetra
Hardy, active tetra with red fins.
Planning your aquarium
The library starting point is 20+ US gallons. Plan for the approximate 2-inch adult size and the species' normal activity, not just its current shop size.
The library suggests a group of at least 6. 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
- Include planting or cover without removing all open swimming space.
