Yes, due to its hardy nature and simple care needs, it's well-suited for those new to fishkeeping.
Does the Savanna tetra require any special care considerations?
While generally easy to care for, maintaining stable water conditions and providing a suitable environment are essential for its well-being.
Care and Environment
Caring for the Savanna tetra involves creating an environment that mirrors its natural habitat to ensure optimal health and coloration.
What is the minimum tank size for a Savanna tetra?
A tank with base dimensions of 60 x 30 cm (approximately 54 liters) is the smallest recommended for housing a group of these tetras.
What are the ideal water parameters for Savanna tetras?
They thrive in temperatures between 20–25°C, with a pH range of 5.5–7.5, and water hardness between 36–215 ppm.
How should the tank be decorated for Savanna tetras?
Incorporate a sandy substrate, driftwood roots, and branches to mimic their natural environment. Adding dried leaf litter can enhance the natural feel and promote beneficial microbe growth.
Filtration should provide a gentle to moderate flow, replicating the slow-moving waters of their native habitat. Lighting can be subdued, with floating plants to create shaded areas, offering the tetras places to retreat and reducing stress.
As omnivores, Savanna tetras accept a variety of foods. A balanced diet should include high-quality flake or micro pellet foods, supplemented with live or frozen options like brine shrimp, micro worms, and daphnia. Incorporating vegetable matter, such as blanched spinach or spirulina flakes, can also be beneficial.
Regular maintenance, including weekly water changes of 20–25%, is crucial to maintain water quality and prevent the buildup of harmful substances. Monitoring water parameters consistently will help ensure a stable environment for the tetras.
Origin and Habitat
The Savanna tetra is indigenous to the Tocantins River basin in South America. In the wild, they inhabit slow-moving tributaries and floodplain waters, thriving among submerged roots, leaf litter, and dense aquatic vegetation. These environments are characterized by soft, slightly acidic water with temperatures ranging from 23–28°C.
What type of water bodies do Savanna tetras inhabit?
They are found in slow-moving tributaries and floodplain waters with abundant vegetation and submerged structures.
How do seasonal variations affect their natural habitat?
Seasonal floods can alter water parameters and availability of food sources, influencing their behavior and breeding patterns.
Why is it important to replicate their natural habitat in an aquarium?
Mimicking their natural environment helps reduce stress, promotes natural behaviors, and enhances their overall health and coloration.
Temperament and Compatibility
Savanna tetras are peaceful, schooling fish that thrive in groups of at least 8–10 individuals. Keeping them in larger groups not only makes them feel more secure but also encourages natural behaviors and displays.
Are Savanna tetras suitable for community tanks?
Yes, their peaceful nature makes them excellent candidates for community aquariums with other similarly sized, non-aggressive species.
What are ideal tank mates for Savanna tetras?
Suitable companions include other small characids, gasteropelecids, lebiasinids, smaller callichthyid or loricariid catfishes, and non-predatory, small-to-medium-sized cichlids.
Can Savanna tetras be kept with larger or aggressive fish?
It's best to avoid housing them with larger or aggressive species, as the tetras may become stressed or preyed upon.
Providing ample swimming space and hiding spots with plants and decorations will help create a harmonious environment, allowing the Savanna tetras and their tank mates to coexist peacefully.
Interesting Facts
The Savanna tetra, while not as widely known as some other tetra species, offers unique characteristics that make it a delightful addition to aquariums.
What is the maximum size of a Savanna tetra?
They typically reach a maximum standard length of 25–35 mm.
How do Savanna tetras contribute to the aquarium ecosystem?
By consuming small invertebrates and algae, they help maintain a balanced ecosystem within the tank.
Are there any notable behaviors exhibited by Savanna tetras?
They are known for their active schooling behavior, often moving in synchronized patterns that add dynamic movement to the aquarium.
Their adaptability and striking appearance have made them a subject of interest among aquarists looking to diversify their tanks with lesser-known species.
