Kuhli loach tank mates

Kuhli loach: peaceful and shy, 3.9 in, kept in groups of 6 or more, swims in the bottom and substrate of the tank and needs about 17 gallons. The list below checks every species in our catalog against it.

Each species is checked against kuhli loaches 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

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

Cherry shrimp
Neocaridina davidi

1.6 in · 4+ gal · 72–75°F · pH 6.5–7.8

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
Amano shrimp
Caridina multidentata

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
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
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.

Clown loach
Chromobotia macracanthus

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
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.

Fairy cichlid
Neolamprologus brichardi
