Also known as the Longfin Red Minor Tetra or Longfin Jewel Tetra, this active South American tetra is best kept in a proper group where its natural shoaling behaviour can be seen. It is hardy and attractive, but it can be fin-nippy if kept in small numbers, so it is best suited to a robust community aquarium rather than a delicate long-finned setup.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cstrong\u003eCommon Name:\u003c\/strong\u003e\u003cbr\u003e\u003cspan\u003eLongfin Serpae Tetra.

The wild Serpae Tetra is native to South America, including the Amazon, Guaporé and Paraguay River basins. In nature, it is associated with slow-moving or stagnant freshwater habitats, especially areas with emergent plants, vegetation and cover near the surface.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cstrong\u003eWater Parameters:\u003c\/strong\u003e\u003cbr\u003e\u003cspan\u003eTemperature: 22–26°C\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003epH Range: 5.5–7.8\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eHardness: soft to moderately hard water\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cstrong\u003eTemperament:\u003c\/strong\u003e\u003cbr\u003e\u003cspan\u003eSemi-aggressive. Serpae Tetras are active, social and can be fin-nippy, especially if kept in too small a group or with slow, long-finned tank mates. They are best kept in good numbers so their energy and hierarchy remain mostly within the shoal.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cstrong\u003eDiet:\u003c\/strong\u003e\u003cbr\u003e\u003cspan\u003eOmnivorous. In the wild, Serpae Tetras feed on worms, small crustaceans, insects and plant matter. In the aquarium they should be offered a varied diet including quality flake, micro pellets, small granules, frozen daphnia, brineshrimp, cyclops, bloodworm and occasional live foods.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cstrong\u003eMinimum Tank Size:\u003c\/strong\u003e\u003cbr\u003e\u003cspan\u003eA practical recommendation is at least 80–100 litres for a proper group, with a 75–90 cm aquarium or larger preferred due to their active behaviour and need for swimming space.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cstrong\u003eBehaviour \u0026amp; Activity:\u003c\/strong\u003e\u003cbr\u003e\u003cspan\u003eThis is an active mid-to-upper level shoaling tetra that should be kept in a group of at least 8, ideally 10 or more. In good numbers, Longfin Serpae Tetras are more confident, display better colour and are less likely to target other fish. They appreciate planted edges, shaded areas, open swimming space and a secure lid, as active tetras may jump when startled.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cstrong\u003eAquarium Category:\u003c\/strong\u003e\u003cbr\u003e\u003cspan style=\"text-decoration: underline;\"\u003eSemi-Aggressive\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eThis species can work well in a robust community aquarium, but it should not be treated as a gentle nano tetra. Suitable tank mates include other active tetras, danios, peaceful barbs, rainbowfish, Corydoras, bristlenose plecos and confident community fish of similar size. Avoid bettas, fancy guppies, long-finned fish, very timid nano species, slow gouramis, angelfish with trailing fins and delicate fish that may be stressed by constant activity.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cstrong\u003eSpecial Requirements or Care Notes:\u003c\/strong\u003e\u003cbr\u003e\u003cspan\u003eBest kept in a mature, well-filtered aquarium with clean water, stable parameters and regular maintenance. Group size is very important with Serpae Tetras, as small groups are much more likely to become nippy or disruptive. Because this is a longfin strain, avoid sharp décor and any tank mates likely to nip fins. Darker substrate, plants and a varied diet will help bring out stronger red colouration.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cstrong\u003eSuitable for:\u003c\/strong\u003e\u003cbr\u003e\u003cspan\u003eBeginner to intermediate fishkeepers\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cstrong\u003eAvailability:\u003c\/strong\u003e\u003cbr\u003e\u003cspan\u003eCommon \/ occasional in trade, usually as captive-bred stock\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003e\u003cstrong\u003eAll images are a visual representation of the fish you will receive, made to be as accurate as possible.
