Pearl gourami tank mates

Pearl gourami: peaceful, 4.7 in, fine on its own, swims in the top and middle of the tank and needs about 26 gallons. The list below checks every species in our catalog against it.

Each species is checked against pearl gouramis both ways: mouth size, fin nipping, temperament, territory, water overlap and keeper reports.

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
Panda corydoras
Corydoras panda
Fits
Friendly armoured catfish that sift the sand in groups; need soft substrate and a group of six or more.
1.6 in · 17+ gal · 72–77°F · pH 6–7.2
Otocinclus
Otocinclus vittatus
Fits
Tiny algae grazers for mature planted tanks; keep six or more and supplement with vegetables.
1.4 in · 17+ gal · 72–79°F · pH 6–7.2
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
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
Blood parrot cichlid
hybrid
Fits
A man-made hybrid cichlid with a round body and a beak-like mouth that barely closes; usually gentle and rarely able to swallow tank mates.
7.9 in · 36+ gal · 72–82°F · pH 6.5–8
Bristlenose pleco
Ancistrus cf. cirrhosus
Fits
The go-to glass cleaner: a compact 5-inch pleco with bushy whiskers on the males that needs a cave and vegetables, not just algae.
4.9 in · 17+ gal · 70–79°F · pH 5.5–7.5
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

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
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
Common pleco
Pterygoplichthys pardalis
Fits
The classic store 'algae eater' that grows to nearly two feet, fouls the water and eats less algae with age; a fish for very large tanks only.

5.5 in · 80+ gal · 79–86°F · pH 5–7
Fairy cichlid
Neolamprologus brichardi

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

Glowlight tetra
Hemigrammus erythrozonus
