GloFish Shark
Epalzeorhynchos bicolor
GloFish Tetra
Gymnocorymbus ternetzi
Glowlight Danio
Danio choprai
Glowlight Tetra
Hemigrammus erythrozonus
The glowlight tetra has a warm golden-orange iridescent stripe running the full body length, glowing like an ember in a planted tank. It is a peaceful, attractive schooling fish that pairs beautifully with dark substrates and dense planting.
Gold Angelfish
Pterophyllum scalare
A captive-bred variety carrying the gold gene, producing a warm golden-yellow body with reduced or absent black barring. The gold colouration intensifies with good nutrition and water quality. A classic show-tank fish that pairs beautifully with dark substrates.
Gold Danio
Danio albolineatus
Gold Medaka
Oryzias latipes var.
Golden selective line of the Japanese ricefish. Suitable for ponds, outdoor tubs, and nano tanks. Extremely tough and easy to breed. Females carry egg clusters before releasing to plants.
Gold Nugget Pleco
Baryancistrus xanthellus
Gold nugget plecos are stunning loricariids with a dark body covered in bright yellow spots and yellow-tipped fins. They are territorial and require warm, oxygen-rich, fast-flowing water with driftwood. They are algae scrapers that also need protein in their diet.
Gold Ring Danio
Danio tinwini
Gold Tetra
Hemigrammus rodwayi
The gold tetra has a distinctive golden-yellow sheen to the body caused by a parasitic infection the fish experiences in the wild — this actually produces the attractive gold iridescence that hobbyists prize. Tank-bred specimens often lack the intense gold but retain a pleasant iridescence. A peaceful, undemanding schooling fish.
Golden Pencilfish
Nannostomus beckfordi
Hardy, golden-bodied pencilfish with a bold red-and-black lateral stripe. The most adaptable pencilfish — tolerates a wider pH range than most. Great for beginner planted tanks.
Gossei Corydoras
Corydoras gossei
Gossei corydoras is a medium-sized species with a golden-tan body adorned with irregular dark markings. It is sometimes called the tail spot cory for the dark blotch at the caudal peduncle. A peaceful schooling species that does well in South American biotope setups with dark substrate and tannin-stained water.
Green Chromis
Chromis viridis
The quintessential schooling reef fish — shimmering apple-green in open water above Acropora. Incredibly hardy and peaceful. Best kept in groups of 6+ for the most natural look.
Green Corydoras
Corydoras aeneus
Green Laser Corydoras
Corydoras sp. 'CW009'
Green Neon Tetra
Paracheirodon simulans
The green neon tetra is the smallest of the three Paracheirodon tetras and one of the most underappreciated. It has a longer, more vivid blue-green stripe with a shorter red patch compared to the cardinal tetra. It is a strict blackwater species requiring soft, very acidic water and is best kept in biotope setups with tannin-stained water and low light.
Green Spotted Puffer
Dichotomyctere nigroviridis
Vivid green-and-black spotted puffer. Requires brackish conditions as an adult. Highly intelligent and inquisitive — needs enrichment and varied diet including snails to wear down its ever-growing beak.
Green Terror Cichlid
Andinoacara rivulatus
Green terror cichlids are large, dramatic fish with vivid turquoise-green scaling and orange-edged fins. Males develop a pronounced nuchal hump with age. Despite the name, they are manageable in species or large community cichlid setups.
Guppy
Poecilia reticulata
Guppies are hardy, colourful livebearers that reproduce readily in captivity. Males display elaborate tails and body patterns to attract females. They adapt to a wide range of water conditions, though clean, well-filtered water is essential to prevent fin disease.
Haraldschultzi Corydoras
Corydoras haraldschultzi
Harlequin Rasbora
Trigonostigma heteromorpha
The harlequin rasbora is recognised by the distinctive black triangular patch on its rear half set against a copper-orange body. Hardy, peaceful, and active in the midwater, it pairs beautifully with planted tanks.
Harlequin Tusk
Choerodon fasciatus
Bold orange-and-white banded wrasse with vivid blue teeth. Impressive predator fish for FOWLR tanks. Australian specimens (red-orange) are more vibrant than Indo-Pacific.
Hastatus Corydoras
Corydoras hastatus
Hillstream Loach
Sewellia lineolata
The Hillstream Loach (Reticulated Hillstream Loach) is a spectacularly patterned torrent fish with a flattened body and enlarged pectoral fins adapted for clinging to rocks in fast-flowing streams. In the aquarium it requires strong water movement, high oxygenation, and cool temperatures mimicking its native Vietnamese mountain streams. It grazes periphyton (algae and biofilm) from hard surfaces and benefits from supplemental feeding with blanched vegetables and spirulina wafers.
Hockey Stick Pencilfish
Nannostomus eques
Distinctive pencilfish that swims at a 45° upward angle with its head tilted toward the surface. Copper-red body with a bold black lateral stripe. Fascinating schooling behaviour in planted tanks.
Honey Gourami
Trichogaster chuna
The Honey Gourami is one of the most peaceful labyrinth fish in the hobby — males develop a rich golden-honey coloration with an orange-red throat and belly when in breeding condition. At 4–5 cm it fits comfortably in nano and small community tanks. Less prone to disease than the Dwarf Gourami and considerably more tolerant of soft, acidic water, making it an excellent alternative for low-tech planted setups.
Hongsloi Dwarf Cichlid
Apistogramma hongsloi
Striking apisto with vivid yellow, red, and blue colouring on males. Highly variable in colour intensity depending on mood and water quality. A showpiece fish for any planted South American biotope.
Horsefaced Loach
Acantopsis dialuzona
Elongated loach with a distinctive long snout for sifting sand. Spends much of its time buried with just its eyes visible. Peaceful and an excellent sand-bed cleaner.
Imitator Corydoras
Corydoras imitator
Jack Dempsey
Rocio octofasciata
Bold, iridescent cichlid covered in electric blue-green spots. Named for the aggressive boxer. One of the most popular American cichlids — easier to keep than its aggressive reputation suggests.
Japan Blue Endler
Poecilia wingei
Japanese Ricefish
Oryzias latipes
Tiny, peaceful fish from Japanese rice paddies. Extremely cold-tolerant — one of the few fish that can be kept outdoors year-round in temperate climates. Egg-hanger that's easy to breed.
Julii Cichlid
Julidochromis transcriptus
Elegant Tanganyikan cichlid with black-and-white chequered markings. Pairs for life and is a devoted parent. Relatively peaceful and a great entry point into Tanganyikan cichlids.
Julii Corydoras
Corydoras julii
The julii corydoras is often confused with the false julii (C. trilineatus) which is more commonly sold. True julii have spots that do not connect into lines. Both are charming, peaceful schooling fish suited to planted community tanks with fine substrate.
Kissing Gourami
Helostoma temminckii
Famous for its lip-locking 'kissing' behaviour — actually a dominance display. Pink or green form available. A voracious algae grazer that also strips soft plants. Grows large.
Kitty Tetra
Hyphessobrycon heliacus
The kitty tetra is a relatively new species to the aquarium trade with a beautiful rosy-pink body and striking red and black finnage. It is closely related to the rosy tetra and shares its peaceful temperament. A charming choice for soft-water planted community tanks, where its delicate colouration glows under warm lighting.
