Table of contents

Introduction

Bloodfin Tetras (Aphyocharax anisitsi) make a commendable addition to any community aquarium, distinguished by their amiable demeanour, vigorous activity, robust constitution, and overall tranquillity. Being one of the larger Tetra species, they do exhibit occasional fin-nipping tendencies, particularly towards more delicate counterparts such as Angelfish or Guppies endowed with intricate fin structures. Despite this aspect, their enduring robustness renders them an appealing choice for novice aquarists. Notably suitable for beginners, this Tetra species adapts adeptly to a diverse spectrum of environmental conditions.

The Bloodfin Tetra thrives in an animated shoaling pattern, thereby necessitating maintenance in groups comprising a minimum of 6 individuals; elevating this to a contingent of ten or more individuals is advised whenever feasible. Due to their inherent nipping propensity, they are ideally paired with other agile, short-finned fish while refraining from cohabitation with species characterized by elaborate finnage.

The aquarium habitat should be richly adorned with abundant vegetation, accompanied by a dark-hued substrate and backdrop to optimize the presentation of their vibrant colouration. Effective filtration is recommended, accompanied by gentle water movement to ensure their well-being. An imperative consideration entails the provision of a secure lid to prevent their propensity for skilled jumping. While acclimatization to a stable room temperature is possible, it's worth noting that showcasing their colours to their fullest extent often necessitates the maintenance of warmer water conditions.

Bloodfin Tetras exhibit a distinctive and refined colouration characterized by silvery-blue body pigmentation complemented by vivid blood-red caudal and anal fins. Notably, certain specimens feature red dorsal and pelvic fins, while others present fins with a translucent quality.

Bloodfin Tetras are found in the freshwater streams and small river tributaries of Brazil, Argentina, Paraguay, Uruguay, and the Parana River Basin.

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 has 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 accepts 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.
