Good tank mates

Neon tetra
Paracheirodon innesi
Fits
The classic community fish: a tight school of electric-blue stripes that suits planted tanks of 15 gallons and up.
1.2 in · 17+ gal · 70–77°F · pH 5–7
Harlequin rasbora
Trigonostigma heteromorpha
Fits
Copper-orange schooling fish with a black wedge; hardy, calm and a good first school for a 15–20 gallon tank.
1.4 in · 17+ gal · 73–81°F · pH 6–7
Fancy guppy
Poecilia reticulata
Fits
Colourful livebearers with flowing tails; prefer harder water and breed readily, so plan for fry.
1.4 in · 13+ gal · 75–81°F · pH 7–8
Cherry shrimp
Neocaridina davidi
Fits
Bright red dwarf shrimp that graze all day and breed in a planted tank; tiny bioload, but fry are snacks for most fish.
1.6 in · 4+ gal · 72–75°F · pH 6.5–7.8
Betta
Betta splendens
Fits
The Siamese fighting fish: one male per tank, warm still water, and no long-finned or nippy tank mates.
2.8 in · 11+ gal · 72–86°F · pH 6–7.5
Angelfish
Pterophyllum scalare
Fits
Tall, graceful cichlids for tall tanks of 30 gallons and up; adults eat neon tetras and shrimp, so stock around them.
3.5 in · 32+ gal · 77–84°F · pH 6–7
Amano shrimp
Caridina multidentata
Fits
The best-known algae-eating shrimp, made famous by Takashi Amano; bigger than cherries and a good fit for planted community tanks.
2 in · 7+ gal · 72–77°F · pH 6.5–7.5
Black neon tetra
Hyphessobrycon herbertaxelrodi
Fits
A peaceful tetra with a bright white-over-black stripe; hardier than the neon tetra and an easy fit in any calm community tank.
1.4 in · 23+ gal · 73–81°F · pH 5.5–7.5
Black widow tetra
Gymnocorymbus ternetzi
Fits
A hardy, deep-bodied tetra with black 'skirt' fins; easy for beginners, but a small group nips the fins of its tank mates.
2.4 in · 22+ gal · 68–79°F · pH 6–7
Blue dolphin cichlid
Cyrtocara moorii
Fits
A sky-blue Malawi cichlid with a fatty forehead hump; calm and sociable over open sand, but no match for boisterous mbuna.
9.8 in · 80+ gal · 77–81°F · pH 8–8.5
Bronze cory
Corydoras aeneus
Fits
The most widely kept cory: a tough bronze-green or albino catfish that shoals along the bottom and handles a broad range of water.
3 in · 23+ gal · 70–81°F · pH 6–8
Cardinal tetra
Paracheirodon axelrodi
Fits
The neon's close cousin, with red running the full length of the belly; a soft, acidic-water schooling fish that likes it warmer than neons.
1.4 in · 17+ gal · 73–81°F · pH 4–6
Cherry barb
Puntius titteya
Fits
One of the most peaceful barbs: males glow cherry red and leave fins alone, making it great for planted community tanks.
2 in · 17+ gal · 73–81°F · pH 6–8
Chinese algae eater
Gyrinocheilus aymonieri
Fits
A popular sucker-mouth 'cleaner' that reaches 11 inches and turns aggressive with age, sometimes rasping the slime coat off other fish.
11 in · 95+ gal · 72–79°F · pH 6–8
Clown loach
Chromobotia macracanthus
Fits
A bold orange-and-black loach that lives 20 years and grows over a foot long, so a proper group needs a 6-foot tank.
15.7 in · 202+ gal · 75–86°F · pH 5–7
Convict cichlid
Amatitlania nigrofasciata
Fits
A tough Central American cichlid that breeds almost anywhere, and is aggressive enough to attack fish several times its size.
5.9 in · 34+ gal · 75–82°F · pH 7–8
Demasoni
Chindongo demasoni (syn. Pseudotropheus demasoni)
Fits
A small blue-and-black striped mbuna with outsized aggression; it attacks much larger fish and is kept only in large, crowded groups.
3 in · 64+ gal · 75–82°F · pH 8.2–8.5
Dwarf gourami
Trichogaster lalius
Fits
A bright little gourami popular with beginners; one male per tank, no bettas, and buy carefully, as imported fish often carry an incurable iridovirus.
3 in · 18+ gal · 72–81°F · pH 6–7.5
Fairy cichlid
Neolamprologus brichardi
Fits
A graceful Tanganyika cichlid with a lyre tail; one pair grows into a family colony that guards its rocks year-round.
3.5 in · 34+ gal · 73–79°F · pH 8–9
Firemouth cichlid
Thorichthys meeki
Fits
A Central American cichlid with a fiery red throat it flares when threatened; fairly calm for a cichlid but territorial when breeding.
4.7 in · 34+ gal · 75–82°F · pH 6.5–8.5
Glowlight tetra
Hemigrammus erythrozonus
Fits
A small, translucent tetra with a glowing orange stripe along its body; peaceful, hardy and at its best in a densely planted tank.
1.6 in · 22+ gal · 75–82°F · pH 6–7.5
Golden mbuna
Melanochromis auratus
Fits
A striped gold mbuna and one of the most aggressive Malawi cichlids; it kills rival males, so plan a crowded harem tank of 55 gallons or more.
4.3 in · 64+ gal · 75–82°F · pH 7.6–8.8
Jewel cichlid
Rubricatochromis bimaculatus (syn. Hemichromis bimaculatus)
Fits
A blazing red West African cichlid that holds its territory year-round and turns extremely aggressive when spawning; best kept as a pair on its own.
5.9 in · 34+ gal · 72–82°F · pH 6–7.8
Kribensis
Pelvicachromis pulcher
Fits
A small West African cichlid whose female has a bright belly; a cave-spawning pair digs pits and guards fry along the bottom.
3.9 in · 23+ gal · 75–81°F · pH 6.5–7
