Offered at around \u003cstrong\u003e3–3.5 cm\u003c\/strong\u003e, these fish are still young and will settle best in a calm, well-maintained aquarium with plenty of swimming space and cover. Like many members of the Hyphessobrycon group, they are most impressive when kept in a proper shoal, where their confidence increases and their colours and behaviour become more natural.\u003c\/p\u003e\u003cp\u003eThis is an excellent choice for aquarists looking for something a little different from standard tetras. Their understated appearance makes them especially attractive in planted tanks, where dark substrate, driftwood and soft lighting help bring out their best. They are generally peaceful, active in the middle water layers, and suitable for a mature community setup with similarly sized, non-aggressive tank mates.\u003c\/p\u003e\u003cp\u003eAt Tropical Fish Co, we supply healthy live fish with a \u003cstrong\u003elive arrival guarantee\u003c\/strong\u003e and \u003cstrong\u003efast UK delivery\u003c\/strong\u003e, so your new fish arrive ready to settle into their new home with the best possible start.\u003c\/p\u003e\u003ch2\u003eCare at a Glance\u003c\/h2\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eCare factor\u003c\/th\u003e\n\u003cth\u003eRecommendation\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eScientific name\u003c\/td\u003e\n\u003ctd\u003e\n\u003cem\u003eHyphessobrycon\u003c\/em\u003e sp. peru\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCommon name\u003c\/td\u003e\n\u003ctd\u003ePeru tetra, Peruvian Hyphessobrycon tetra\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAdult size\u003c\/td\u003e\n\u003ctd\u003eApprox. 4–5 cm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTemperament\u003c\/td\u003e\n\u003ctd\u003ePeaceful\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCare level\u003c\/td\u003e\n\u003ctd\u003eModerate\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMinimum tank size\u003c\/td\u003e\n\u003ctd\u003e80 litres for a shoal\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTemperature\u003c\/td\u003e\n\u003ctd\u003e22–27°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003epH\u003c\/td\u003e\n\u003ctd\u003e6.0–7.5\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWater hardness\u003c\/td\u003e\n\u003ctd\u003eSoft to moderately soft\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDiet\u003c\/td\u003e\n\u003ctd\u003eOmnivore\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTank zone\u003c\/td\u003e\n\u003ctd\u003eMiddle\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch2\u003eOrigin \u0026amp; Natural Habitat\u003c\/h2\u003e\u003cp\u003e\u003cem\u003eHyphessobrycon\u003c\/em\u003e species from Peru are typically associated with slow-moving tributaries, forest streams, floodplain waters and blackwater-influenced habitats in the Amazon basin. These environments are often shaded by overhanging vegetation, rich in leaf litter, and naturally soft and slightly acidic. Water clarity can vary from tea-coloured blackwater to clearer, gently flowing streams, but the common thread is a warm, calm environment with plenty of cover.\u003c\/p\u003e\u003cp\u003eIn nature, small tetras like this spend much of their time in loose shoals, feeding on tiny invertebrates, plant matter and organic detritus. Replicating these conditions in the aquarium helps them feel secure and display more natural behaviour. A planted aquascape with roots, branches and open swimming areas is ideal.\u003c\/p\u003e\u003ch2\u003eTank Setup \u0026amp; Water Parameters\u003c\/h2\u003e\u003cp\u003eFor best results, keep \u003cstrong\u003eHyphessobrycon sp. peru\u003c\/strong\u003e in a mature aquarium of at least \u003cstrong\u003e80 litres\u003c\/strong\u003e, though larger is always better if you want a fuller shoal and a more stable environment. These fish are active but not boisterous, so a long tank with open midwater space is preferable to a very tall setup. A group of \u003cstrong\u003e8 or more\u003c\/strong\u003e is strongly recommended; smaller numbers can make them shy and reduce their natural behaviour.\u003c\/p\u003e\u003cp\u003eUse a fine dark substrate if possible, as this helps reduce stress and enhances their appearance. Add live plants such as \u003cem\u003eCryptocoryne\u003c\/em\u003e, \u003cem\u003eMicrosorum\u003c\/em\u003e, \u003cem\u003eVallisneria\u003c\/em\u003e and floating plants to create dappled light and secure areas. Driftwood, leaf litter and branches can further mimic their natural habitat. Gentle filtration is best, with good oxygenation but no harsh current. Regular maintenance is essential: weekly water changes, stable temperature and low nitrate levels will keep them in top condition.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eRecommended parameters:\u003c\/strong\u003e temperature 22–27°C, pH 6.0–7.5, with soft to moderately soft water. They can adapt to slightly broader conditions if acclimated carefully, but stability matters more than chasing exact numbers. Avoid sudden changes in temperature or chemistry, and always quarantine new fish where possible before adding them to the display tank.\u003c\/p\u003e\u003ch2\u003eFeeding Guide\u003c\/h2\u003e\u003cp\u003eThese tetras are omnivorous and will accept a wide range of prepared foods. A varied diet is the key to long-term health and good colour. Offer a quality micro pellet or small flake as the staple, then supplement with frozen or live foods such as daphnia, baby brine shrimp, cyclops and bloodworm. Small, frequent feedings are preferable to one large meal, especially for younger fish.\u003c\/p\u003e\u003cp\u003eAs with most tetras, overfeeding should be avoided. Feed only what they can consume in a couple of minutes, once or twice daily. A varied diet supports immune health, growth and breeding readiness, and helps maintain the subtle natural patterning that makes this species so appealing.\u003c\/p\u003e\u003ch2\u003eTank Mates \/ Compatibility\u003c\/h2\u003e\u003cp\u003e\u003cstrong\u003eHyphessobrycon sp. peru\u003c\/strong\u003e is best kept with peaceful, similarly sized fish that enjoy comparable water conditions. Good companions include other small tetras, rasboras, peaceful pencilfish, Corydoras catfish, small plecos such as \u003cem\u003eAncistrus\u003c\/em\u003e, and gentle dwarf cichlids in suitably sized aquariums. They also work well in planted community tanks with shrimp, though very small shrimp fry may be at risk.\u003c\/p\u003e\u003cp\u003eBecause they are a shoaling species, they should not be kept with large, aggressive or overly boisterous fish. Fin-nippers and fast, dominant species can cause stress and prevent them from settling. Avoid mixing them with large cichlids, barbs known for nipping, or predatory fish that may view them as food. A calm community with plenty of visual cover will bring out the best in them.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCompatibility tip:\u003c\/strong\u003e the more secure the environment, the more active and confident this tetra will become. Keep them in a proper group and they will spend more time in the open, showing natural shoaling behaviour.\u003c\/p\u003e\u003ch2\u003eWhy Buy from Tropical Fish Co\u003c\/h2\u003e\u003cp\u003eAt Tropical Fish Co, we specialise in healthy, high-quality livestock for aquarists who want the best possible start with their new fish.
