Cherry Tetra Care Guide - Aquarium Setup, Diet & Breeding

Cherry Tetras are small, elegant characins with a slender body and attractive reddish to cherry-coloured tones that become more pronounced when the fish are settled and displaying. Their coloration can vary between populations, and males often develop the richest red hues, especially across the body and fins.

Active but generally peaceful, they spend much of their time in the middle levels of the aquarium. A proper group gives them confidence and encourages natural shoaling, courtship displays and occasional bursts of activity without making them aggressive toward other fish.

In the wild, these tetras are associated with quiet, plant-lined waters beneath overhanging vegetation. Fallen leaves, branches and tannins can create a subdued environment with soft light, dark water and plenty of cover, although captive-bred or commercially acclimated specimens often adapt to a wider range of conditions.

The name Cherry Tetra is used in the aquarium trade for an undescribed or incompletely identified Hyphessobrycon species, so appearance and exact locality can differ. They are nevertheless valued as colourful, sociable community fish that bring movement and subtle red colour to a planted aquarium.

Cherry Tetras are believed to originate from slow-moving, shaded tributaries and forest streams in the western Amazon region of South America, particularly Peru. As Hyphessobrycon sp. remains an unresolved identification, the precise native range may vary between commercially traded populations.

A group of Cherry Tetras should be kept in an aquarium of at least 60 litres, with a footprint around 60 by 30 cm or larger. Use gentle filtration and water movement, open swimming space and dense planting around the sides and back, with driftwood, roots or leaf litter providing shaded retreats. A dark sand or fine-gravel substrate helps the fish feel secure and makes their warm coloration stand out. Leave some unobstructed midwater space for shoaling, and use a secure lid because small tetras may jump.

Cherry Tetras reach a maximum adult length of about 4 cm (1.6 inches). Males are often slightly longer and noticeably more slender than females, while females may appear deeper-bodied when carrying eggs.

Cherry Tetras are omnivores and thrive on a varied diet of quality small flakes or micro-pellets supplemented with frozen or live foods such as baby brine shrimp, daphnia, cyclops and mosquito larvae. Feed appropriately sized portions once or twice daily, offering enough for the group to consume promptly. Fine foods are particularly useful for young fish and help bring out the species' natural colour and condition.

Cherry Tetras are peaceful and suit community aquariums with similarly calm fish, including small rasboras, other gentle tetras, pencilfish, kuhli loaches, Corydoras and peaceful dwarf shrimp. They should not be housed with large, predatory or highly boisterous species, nor with fin-nipping fish that may harass them. Keeping them in a good-sized group helps prevent nervousness and limits attention being directed toward other tankmates.

Cherry Tetras are egg-scattering characins that can be bred in a separate, dimly lit spawning aquarium containing fine-leaved plants or spawning mops. Condition a group with plenty of small live or frozen foods, then introduce the adults when females are full of eggs. Spawning usually occurs among the plants, after which the adults should be removed because they may eat the eggs. The eggs hatch in roughly 24 to 36 hours, and the tiny fry can be raised on infusoria or other suitably fine first foods before progressing to newly hatched brine shrimp.

Males are generally slimmer and develop stronger red coloration, particularly when mature or displaying. Females are usually fuller through the abdomen and can look rounder when carrying eggs, with less intense coloration in many specimens.
