Tetras
Freshwater Tetras at Petco
Tetras are one of the most popular freshwater fish species, known for their vibrant colors, peaceful nature, and active schooling behavior. Whether you’re starting a new aquarium or adding to an existing community tank, freshwater tetras are a great choice for both beginner and experienced fish keepers. At Petco, you’ll find a variety of tetra species that bring movement and beauty to any aquatic setup.
Choosing the Right Tetra for Your Tank
Tetras come in a range of colors, sizes, and temperaments. Some of the most popular species include:
- Neon Tetras – Small, brightly colored fish with a shimmering blue and red body. Perfect for peaceful community tanks.
- Cardinal Tetras – Similar to neon tetras but with a longer red stripe along their body, making them even more eye-catching.
- Glowlight Tetras – Feature a soft orange glow and thrive in planted aquariums with dim lighting.
- Black Skirt Tetras – Hardy fish with a unique black-and-silver body, great for beginner aquarists.
- Rummy Nose Tetras – Recognizable by their bright red faces and sleek silver bodies, they are excellent for schooling.
Caring for Tetras in a Freshwater Aquarium
Tetras are social fish that thrive in well-maintained environments with stable water conditions. Here’s what to consider:
- Tank Size – A 10-gallon tank is the minimum for a small school, but larger tanks (20+ gallons) provide more space for them to thrive.
- Water Conditions – Tetras prefer temperatures between 72-80°F, a pH range of 6.0-7.5, and soft, slightly acidic water.
- Schooling Behavior – Always keep tetras in groups of at least six to reduce stress and encourage natural schooling.
- Compatible Tank Mates – Tetras do well with other peaceful fish like guppies, rasboras, corydoras, and dwarf gouramis.
