2. Caring for Cardinal Tetras:
To ensure optimal care for cardinal tetras in your aquarium, check out the following care tips:
-
Aquarium Setup: Provide your cardinal tetras with a well-stocked aquarium with plenty of hiding spots and swimming areas. For a small group of cardinal tetras, a tank of at least 10 gallons is recommended. Use a fine-grained substrate and add live or artificial plants for cover and enrichment.
-
Water Parameters: Cardinal tetras thrive in slightly acidic to neutral water with a pH range of 5.5 to 7.0 and temperatures of 72°F to 82°F (22°C to 28°C). Maintain moderate hardness and provide adequate filtration to keep water clean and well-oxygenated.
-
Tankmates: Cardinal tetras are peaceful fish that can coexist with a variety of tankmates, including other peaceful community fish species. Avoid keeping them with aggressive or flipper-biting animals, which could harass or injure them.
-
Feeding:Offer a varied diet consisting of high-quality flake foods, kibble and the occasional treat such as frozen or live food. Supplement their diet with protein-rich foods such as bloodworms, brine shrimp, and daphnia to improve their coloration and overall health.
3. Aquarium care:
-
Routinely change the water by 25-30% every one to two weeks to maintain optimal water quality and remove accumulated waste.
-
Clean the substrate and decorations during water changes to remove debris. Use a gravel vacuum to suck waste from the substrate without disturbing the fish.
-
Monitor water parameters regularly using a reliable test kit and make adjustments as necessary to maintain stable conditions.
