Table of contents

Introduction

Bloodfin Tetras, (Aphyocharax anisitsi) make an excellent addition to any community aquarium, boasting a friendly, active, hardy, and relatively peaceful nature. As one of the larger Tetra species, they may occasionally nip at the fins of more delicate fish like Angelfish or Guppies with elaborate fin structures. However, they remain a popular choice for beginners, given their hardiness. Providing plant cover and incorporating floating species to diffuse light can help create a more comfortable environment for them. Bloodfin Tetras are social creatures and best kept in groups of five or more, primarily inhabiting the upper and middle water layers. When isolated, they may exhibit more introverted behavior. For a vibrant and harmonious aquarium community, consider keeping a mixed shoal of Characids, small Loricariids, and Corydoras Catfish. The combination of these fish offers a dynamic and visually captivating display of diverse species that thrive in a collective environment. Bloodfin Tetras, in particular, add a playful energy and vibrant coloration that complements the more subdued hues of the Loricariids and the graceful movements of the Corydoras catfish. In addition to their visual appeal, Loricariids and Corydoras catfish offer practical benefits, including effective algae control and a diligent cleanup crew that can help maintain water quality and a healthy aquarium environment. Overall, incorporating these species into a mixed shoal can create a stunning and lively display that is both aesthetically pleasing and beneficial for the aquarium 's overall health and balance. The subtle yet striking coloration of Bloodfin Tetras, with their silvery-blue bodies and vibrant blood-red fins, adds to their appeal and popularity among aquarium enthusiasts.

Breeding

Bloodfin Tetras are oviparous fish that appreciate seclusion during the reproductive process. Consequently, a designated breeding tank with dim lighting, abundant plant life, and slightly acidic water is recommended. To promote spawning and enhance their overall condition, it is essential to provide them with nutrient-rich, high-quality food. During breeding, the male will escort the female over the plants, where she will deposit between 300 and 500 transparent eggs on broad-leaved vegetation. These eggs are expected to hatch within a 24-hour period. To ensure the eggs ' safety, it is crucial to remove the parent fish after the female has laid her eggs, as they are prone to consume them. The eggs are anticipated to hatch within 24 hours. After the fry have depleted their yolk sacs, it is advisable to provide them with infusoria as an initial food source. As they grow and develop, the fry should then be fed baby brine shrimp

Diet & feeding

Bloodfin Tetras exhibit a versatile palate and readily accept a wide range of food offerings. A staple diet consisting of dried food, such as flakes or micro pellets, and vegetables, is recommended. However, to ensure a well-balanced and healthy diet, occasionally supplement their meals with live and frozen food options, including bloodworms, mosquito larvae, and brine shrimp.
