A highly active, schooling cyprinid famous for its striking black stripes and infamous reputation as a fin-nipper. They are boisterous and must be kept in larger groups (6+) to keep their pecking order internal. They should never be housed with slow-moving or long-finned tankmates like Bettas, Guppies, or Angelfish.

Available Varieties
Each variety inherits the species defaults above. Only differences are highlighted.
Standard (Wild Type)
The classic, silver-gold body with four prominent vertical black stripes and red accents on the fins and snout.
Same care requirements as the base species
Also known as: Regular, Striped
Green / Moss Barb
A popular color morph where the black stripes merge and widen to cover the entire body in a beautiful metallic green or blue/black sheen. Care and behavior are identical to the wild type.
Same care requirements as the base species
Also known as: Green Tiger Barb, Moss Green, Mutant Barb
Albino / Gold
Lacks black pigment, resulting in a yellow/orange body with white bands. Can be slightly more sensitive to excessively bright lighting, but otherwise shares the same boisterous temperament.
Same care requirements as the base species
Also known as: Albino Tiger Barb, Golden, Blushing
GloFish (Fluorescent)
Genetically modified with jellyfish/coral proteins to express bright fluorescent colors under blue/actinic lighting. Temperament and care requirements remain identical to standard Tiger Barbs.
Same care requirements as the base species
Also known as: Glo, Electric Green, Starfire Red, Sunburst Orange, Galactic Purple
Long-Finned
Selectively bred for highly extended fins. Ironically, while they are still fin-nippers themselves, their long fins make them slower swimmers and susceptible to being nipped by standard short-finned Tiger Barbs. Requires slightly less flow.
Differs in 2 traits from base species
Also known as: Veiltail Tiger Barb, Longfin
Tiger Barb Care Guide Summary
The Tiger Barb, scientifically known as Puntigrus tetrazona, belongs to the Cyprinids family group. Adults reach a maximum size of approximately 7 cm and have a compressed body shape with a moderate growth rate. Classified as semi-aggressive, this species primarily occupies the mid-level and bottom zones of the aquarium and produces a medium level of biological waste.
To thrive, the Tiger Barb requires a freshwater only aquarium with a minimum volume of 80 litres and a tank length of at least 80 cm. Water temperature should be maintained between 20°C and 26°C, with a pH range of 6–8 and a general hardness of 1–15 dGH. A moderate water flow is preferred. An aquarium test kit can help you monitor these values.
The Tiger Barb is a rewarding species to keep, provided its core environmental needs are met. This species is available in 5 varieties: Standard (Wild Type), Green / Moss Barb, Albino / Gold, GloFish (Fluorescent), and Long-Finned. Each may differ slightly in size, temperament, or care needs, so it is worth checking the specific requirements of the variety you plan to keep.
Tiger Barb Habitat Setup
When setting up an aquarium for the Tiger Barb, a moderate water flow best suits their natural preferences. Because this species occupies the mid-level and bottom zones, the aquarium layout should prioritise open swimming space in the centre of the tank for free movement and sufficient floor space with hiding spots among rocks, wood, or dense planting. Useful additions include dense planting to provide cover, break sightlines, and reduce stress.
Tiger Barb Compatibility Notes
Classified as semi-aggressive, the Tiger Barb is a schooling species that feels most secure in a sizeable group, where natural shoaling behaviour reduces stress and brings out their best colours. When choosing tankmates, avoid housing with slow-moving or long-finned species that may become targets for fin nipping, conspecific aggression can be intense, especially in smaller tanks, shy or slow-feeding tankmates may be outcompeted at feeding time, and their energetic swimming style may stress more sedentary or timid species. Selecting tankmates that favour different water layers from the mid-level and bottom zones can help reduce competition and territorial overlap.

Tiger Barb Feeding & Diet Considerations
The Tiger Barb will eat fry, so breeding efforts in the same tank are unlikely to succeed and is an aggressive eater that may prevent timid tankmates from getting enough food — target feeding or simultaneous feeding at opposite ends of the tank can help.

Similar Species
Cherry Barb
Puntius titteya
A peaceful, schooling cyprinid endemic to the shaded streams of Sri Lanka. Unlike many of its barb cousins, the Cherry Barb is not a fin-nipper and makes an excellent community fish. They thrive in heavily planted aquariums with subdued lighting and leaf litter. Males display a striking cherry-red color, especially during spawning.
Rosy Barb
Pethia conchonius
A hardy, active, and colorful subtropical schooling fish. Known for the male's striking rosy-red breeding dress, while females are more golden/silver. They are voracious eaters, very active swimmers, and can be fin-nippers if kept in too small a group. Best kept in cooler water compared to tropical species. The Long Finned morph is also popular but requires gentler flow.
Serpae Tetra
Hyphessobrycon eques
A striking, deep-red schooling fish known for its highly active nature. While hardy and beautiful, Serpae Tetras are notorious fin-nippers. This behavior is usually localized within their own pecking order if kept in large enough schools (8+), but they should never be housed with slow-moving or long-finned tank mates like Bettas, Angelfish, or Gouramis.
Odessa Barb
Pethia padamya
A highly active, stunning schooling fish known for the brilliant red lateral stripe running across the males. Originating from central Myanmar, they thrive in slightly cooler, sub-tropical water compared to typical tropical fish. They are robust and peaceful when kept in proper shoals, but may nip fins if stressed or kept in numbers too small.
Red Tailed Black Shark
Epalzeorhynchos bicolor
A striking and highly active bottom-dwelling cyprinid known for its jet-black body and vibrant red tail. While beautiful, they are notoriously territorial, especially toward their own kind, similar-looking species (like Rainbow Sharks), and sometimes other bottom-dwellers. They must be kept as the only 'shark' in the tank and require a large footprint with plenty of caves and broken sightlines.
Tinfoil Barb
Barbonymus schwanenfeldii
A large, active, and schooling riverine species that quickly outgrows standard aquariums. Known for their metallic silver scales and red fins. They are notoriously skittish, robust eaters, and will consume almost any live plant or small fish that fits in their mouths. A massive tank with strong filtration is strictly required.
