Peacock Cichlid
Aulonocara spp.
Peacock cichlids are among the most colourful freshwater fish, with males displaying brilliant blues, yellows, and reds. They are relatively peaceful for cichlids and suited to species tanks or Malawi community setups with similar temperament fish.
Peacock Endler
Poecilia wingei
Peacock Gudgeon
Tateurndina ocellicauda
Gem-like small fish with iridescent blue, red, and yellow markings and an eyespot on the tail. One of the most beautiful small freshwater fish. Easy to breed in caves.
Pearl Danio
Danio albolineatus
Pearl danios have an iridescent, pearlescent sheen with subtle pink-orange highlights along the flanks. They are extremely hardy, cold-tolerant, and make excellent dither fish for livebearers and other community species. Fast and peaceful.
Pearl Gourami
Trichopodus leerii
The pearl gourami is one of the most elegant community fish, adorned with a pearlescent spotted pattern and a dark lateral stripe. It is a labyrinth fish that breathes surface air, so a tight-fitting lid is recommended. Males can be mildly aggressive toward each other, but generally coexist peacefully in larger tanks.
Pearlscale Angelfish
Pterophyllum scalare
A captive-bred variety expressing the pearlscale gene, which causes each scale to have a raised, pearlescent centre giving the fish a textured, almost jewelled appearance. Often combined with other colour genes (gold, marble, koi) to produce striking show specimens.
Penguin Tetra
Thayeria boehlkei
The penguin tetra is immediately recognised by its bold black stripe that runs down the lower body and into the lower caudal lobe β and by the unique way it holds its body at a nose-up angle while swimming. This head-up posture gives schools a distinctive, elegant appearance. A hardy, peaceful fish that suits most community setups.
Peppered Corydoras
Corydoras paleatus
Peppered corydoras are popular bottom-dwelling catfish that sift through substrate in search of food. They are highly social and should be kept in groups of at least six. Fine sand substrate is essential to protect their sensitive barbels from abrasion.
Pictus Catfish
Pimelodus pictus
Active, silver catfish with black spots and long barbels. Schools in the wild so keep in groups of 3+. A mid-water swimmer unlike most catfish. Will eat small fish that fit in its mouth.
Plakat Betta
Betta splendens 'Plakat'
The Plakat (from the Thai word for fighting fish) retains the shorter, rounder fin shape of wild Betta splendens, close to the original form before centuries of selective breeding. It is a more active, stronger swimmer than long-finned varieties and is less prone to fin damage and disease. Plakats are popular in Thailand, where fighting fish culture originated, and make excellent display fish in planted tanks.
Platy
Xiphophorus maculatus
Platies are cheerful, colourful livebearers available in a wide range of colour morphs. They are very beginner-friendly and tolerant of a broad range of water conditions, preferring slightly hard, alkaline water. Females give birth to live fry roughly every 28 days, so population management may be necessary.
Polystictus Corydoras
Corydoras polystictus
A small, attractively marked corydoras covered in small dark spots over a pale body. C. polystictus is a peaceful, undemanding species that adapts well to a range of water conditions. It is an active forager and looks charming in a planted aquarium with a dark sand substrate that shows off its spotted pattern.
Pygmy Corydoras
Corydoras pygmaeus
One of the smallest corydoras species, pygmy corydoras are unusual in that they often swim in the midwater rather than staying on the bottom. They form tight shoals and look stunning in large groups in nano and planted aquariums.
Pygmy Rasbora
Boraras maculatus
Tiny orange-red rasbora with distinctive black spots. Often confused with Boraras brigittae but slightly larger and more orange. Perfect for blackwater nano scapes. Peaceful and undemanding.
Rabauti Corydoras
Corydoras rabauti
Red Chest Endler
Poecilia wingei
Red Neon Blue Eye
Pseudomugil luminatus
The red neon blue eye is arguably one of the most striking nano fish in the hobby. Males are decorated with vivid orange-red fins edged in black and white, topped with the signature brilliant blue eyes of the genus. It became popular after viral aquascaping videos. Best kept in species or nano setups with very small, calm tankmates.
Reticulated Hillstream Loach
Sewellia lineolata
Striking loach with bold reticulated patterning and a flattened body adapted for fast-flowing streams. Needs high oxygen, strong flow, and cool water. A showstopper in a hillstream biotope.
Reticulatus Corydoras
Corydoras reticulatus
Rope Fish
Erpetoichthys calabaricus
Prehistoric-looking eel-like fish with a series of dorsal finlets. Peaceful with fish too large to swallow. Nocturnal. Can breathe air and will escape through any gap.
Rosetail Betta
Betta splendens 'Rosetail'
The Rosetail Betta is an extreme variation of the Halfmoon with excessive branching of fin rays that causes the tail to ruffle and overlap, resembling rose petals. While visually spectacular, the over-developed fins are heavy and fragile, making the fish a weaker swimmer and more susceptible to fin rot, tearing, and spinal curvature. Best kept in very clean, still water and considered a display specimen.
Rosy Barb
Pethia conchonius
Rosy barbs are large, hardy barbs with males turning a vivid pink-red during breeding. They are cold-tolerant, active, and peaceful in larger groups, though they may nip fins of long-finned fish. An excellent choice for cooler community aquariums.
Rosy Tetra
Hyphessobrycon rosaceus
The rosy tetra has a lovely soft pink to rosy body with a black and white dorsal fin and red-tipped fins that intensify with maturity and condition. Males develop a tall, flag-like dorsal fin. It is an elegant, peaceful fish that is slightly rarer in the hobby than it deserves to be, and looks beautiful in soft-water planted tanks.
Royal Pleco
Panaque nigrolineatus
Royal plecos have striking dark striping on a grey-brown body and spoon-shaped teeth adapted for rasping wood. Driftwood is an essential part of their diet and tank dΓ©cor. They grow large and require spacious tanks with powerful filtration.
Rummy Nose Tetra
Hemigrammus rhodostomus
Named for its distinctive red nose and black-and-white striped tail, the rummy nose tetra is a stunning schooling fish that forms tight, coordinated shoals. It is more sensitive to water quality than the neon tetra and requires soft, warm, acidic conditions to look and behave at its best. The intensity of the red colouration serves as a reliable water quality indicator.
Salt & Pepper Corydoras
Corydoras habrosus
One of the three 'dwarf' corydoras species, C. habrosus reaches just 3 cm and has a distinctive row of dark blotches along its flanks. It is more active in the midwater than most corydoras and is ideal for nano planted tanks. Groups of 10+ will show confident, exploratory behaviour and make excellent companions for small shrimp.
Salvin's Cichlid
Cichlasoma salvini
Vividly coloured medium cichlid with yellow and turquoise markings. Aggressive, especially when breeding. Hardy and tolerant of a range of water conditions.
Sawbwa Barb
Sawbwa resplendens
Graceful, slender fish with a translucent body and vivid red snout and tail on males. Endemic to Inle Lake β prefers cooler, harder water than most aquascaping fish. Stunning in large groups.
Scarlet Badis
Dario dario
Jewel of nano tanks β males are deep red with vivid blue-edged scales. Only 0.8 inches. Refuses dry food for most keepers; needs live or frozen micro prey. Worth every effort.
Schwartzi Corydoras
Corydoras schwartzi
Schwartzi corydoras has a distinctive pattern of dark spots and a prominent black stripe through the eye. It is an active, peaceful schooling fish that spends most of its time foraging along the bottom. Well suited to soft, acidic planted tanks.
Senegal Bichir
Polypterus senegalus
Ancient, armour-plated fish that walks along the bottom on its fins. Breathes air using a primitive lung. Peaceful with fish too large to swallow. Fascinating species.
Serpae Tetra
Hyphessobrycon eques
Serpae tetras are vivid red fish with a distinctive black comma-shaped shoulder mark. They are hardy and bold, but known to be fin-nippers especially in small groups β keep 10 or more to redirect aggression within the school.
Severum
Heros severus
Large, deep-bodied cichlid with a friendly temperament for its size. Comes in green, gold, and red colour variants. Often bonds strongly with its keeper and will hand-feed.
Shell Dweller Cichlid
Lamprologus ocellatus
Tiny Tanganyikan cichlid that lives inside empty snail shells. Males are larger and guard a harem of shell-dwelling females. Perfect for a dedicated shell-dweller nano tank.
Siamese Algae Eater
Crossocheilus oblongus
The Siamese Algae Eater is one of the few fish that will actively consume black beard algae (BBA), making it highly sought after by planted tank hobbyists. It is a streamlined, active fish with a distinctive black horizontal stripe from snout to tail. Unlike the similar-looking Flying Fox, it is a true algae specialist rather than just a grazer. Best kept singly or in groups; young fish are more active algae eaters than adults.
Silver Angelfish
Pterophyllum scalare
The classic wild-type angelfish with a silver body and bold black vertical bars. Its triangular profile and long trailing fins make it a centrepiece fish. Prefers tall tanks with vertical driftwood or broad-leaf plants that mimic Amazonian floodplains. Semi-aggressive during spawning but generally peaceful with similarly sized tank mates.
