False Rummynose Tetra Care Guide - Aquarium Setup, Diet & Breeding

False Rummynose Tetras are elegant, streamlined characins with a silvery body, a vivid red snout and red markings extending across the front of the head. Their tail is patterned with striking black-and-white bands, giving a healthy shoal a lively, flashing appearance as it moves through the aquarium.

This species is peaceful, active and strongly social. In a suitably sized group, the fish swim together through the middle levels of the water, often changing direction in unison while remaining less boisterous than many larger tetras.

In the wild, False Rummynose Tetras are associated with quiet tributaries, flooded forest and tannin-stained Amazonian waters. Leaf litter, submerged roots and dense marginal vegetation provide cover and create the subdued, complex surroundings typical of their natural habitat.

Petitella georgiae is regularly confused with the true Rummynose Tetra and the Brilliant Rummynose Tetra, as all three have red facial markings and a striped tail. Close inspection of the head markings, body shape and tail pattern is often needed for confident identification, particularly in shops where the names are used inconsistently.

False Rummynose Tetras are native to the western Amazon basin in South America, particularly the upper Amazon and tributary systems of Peru and adjoining areas. They inhabit slow-moving forest streams and flooded waterways with clear to tea-coloured water.

A group should have at least 80 litres, with a tank around 90 cm long preferred to provide a generous swimming run. Use a soft sand or fine rounded-gravel substrate, subdued lighting, dense planting, driftwood and leaf litter to create sheltered, naturally shaded areas while leaving open water at the front and centre. Gentle filtration and unobstructed circulation suit their preference for calm, well-oxygenated water.

False Rummynose Tetras reach approximately 5 cm (2 inches) in adult length. Females are usually slightly larger and deeper-bodied than males.

False Rummynose Tetras are omnivores that accept quality small flakes, micro-pellets and granules. Their diet should be varied with regular offerings of frozen or live foods such as baby brine shrimp, daphnia, cyclops and mosquito larvae. Small portions are best suited to their mouths and help ensure that every fish receives food.

False Rummynose Tetras are peaceful community fish and can be kept with similarly sized, non-aggressive species such as cardinal tetras, ember tetras, harlequin rasboras, pencilfish, peaceful Corydoras and small peaceful Loricariid catfish. They should not be housed with large cichlids, predatory fish, fin-nippers or boisterous species that may intimidate them or treat them as prey.

False Rummynose Tetras are egg-scattering fish that breed most successfully in a separate, dimly lit spawning aquarium with soft, acidic water and fine-leaved plants or a spawning mop. A conditioned pair or small group can be introduced for spawning, 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 initially need infusoria or another suitably fine first food before progressing to larger foods.

Females are generally fuller through the abdomen and slightly larger, particularly when carrying eggs. Males tend to be slimmer, although the differences are subtle and difficult to judge in young fish.
