Rummy-nose tetra

The rummy-nose tetra (Petitella rhodostoma), also known as the rednose tetra, is a species of freshwater ray-finned fish belonging to the family Acestrorhamphidae, the American characins. This species occurs in South America, where it is restricted to the lower basin of the Amazon in Brazil. This is a popular species in the aquarium hobby. the rummy-nose tetra is a schooling fish, which exhibits tight schooling behaviour both in the wild and in the aquarium. Consequently, these fishes should be maintained in groups of no fewer than six individuals, with larger numbers being preferable where space permits; these tetras prefer about a 25 gallon/80 litre aquarium. the temperature range for maintenance being 24 to 31 °C (75 to 88 °F), with the fishes sometimes requiring temperatures as high as 33 °C (91 °F) for breeding. panda corydoras would be a bad choice of companion, as these fishes prefer lower temperatures, and there is little overlap in the temperature ranges of the two species. Many fish can be kept with rummy-nose tetras, some including smaller gourami, other tetras, barbs, danios, Australian rainbows, and various catfish, such as Ancistrus. The rummy-nose tetra cannot be kept with other popular ornamental fishes, such as African cichlids, as they require very different water parameters. The water chemistry preferred by these fishes, as might be inferred readily from that of the wild habitat, is soft, acidic water (hardness no higher than 6° dH and pH around 6.4–7.0 is preferred). However, for maintenance purposes, the pH of the aquarium water can range from 5.6 to 7.4. However, if captive reproduction is to be attempted, the rummy-nose tetra needs soft, acidic water. A planted aquarium is welcomed by these fishes, particularly if the plants include fine-leaved species such as Cabomba and Myriophyllum. #aquarium #aquariumfish #rummynosetetra
