Cherry barb care guide
The cherry barb is a calm, 2 in (5 cm) barb from Sri Lanka whose males turn deep cherry red. Unlike most barbs it rarely bothers tank mates. Keep six or more in a well-planted 15 gallon (57 L) tank.
Cherry barbs need a tank of at least 15 gallons (57 L), a group of 6 or more, and water at 23–27°C (73–81°F) with a pH of 6–7.5. They grow to about 5 cm (2 in) and are peaceful.

Tank setup
A group of six needs at least a 15 gallon (57 L) tank about 24 in (60 cm) long. Plant it densely and add floating plants to soften the light. Cherry barbs feel safe with cover around them and show far better color than in a bare tank. A dark substrate and gentle filter flow suit them.
How many cherry barbs in a tank?
The smallest common tank that suits cherry barbs is a 15 gallon. Here is roughly how many fit in each size when they are the only fish, based on adult size and waste output. Leave room if you want tank mates.

| 10 gallon | Too small |
| 15 gallon | 6–14 |

Tank and equipment
- 15 gallon aquarium (tank or kit) (opens Amazon in a new tab)Bigger tanks are more stable and easier for beginners. How to choose
- Adjustable heater, 50 W (opens Amazon in a new tab)Holds about 77 °F (25 °C) in a room at 65 °F (18 °C). How to choose
- Aquarium thermometer (opens Amazon in a new tab)Check it daily: heaters can fail stuck on or off. How to choose
- Hang-on-back filter rated 60–90 GPH (opens Amazon in a new tab)Community tank: 4–6 times the tank volume per hour. How to choose
- About 35 lb of aquarium gravel (opens Amazon in a new tab)Enough for a layer about 2 in (5 cm) deep. Smooth gravel suits most community fish. How to choose
- Water conditioner (dechlorinator) (opens Amazon in a new tab)Removes chlorine and chloramine from tap water. Seachem Prime is a popular, concentrated choice. How to choose
- Liquid test kit (ammonia, nitrite, nitrate, pH) (opens Amazon in a new tab)Liquid kits are more accurate than strips. The API Freshwater Master Test Kit is the common choice. How to choose
- Gravel vacuum (siphon) (opens Amazon in a new tab)Cleans the gravel and does the water change in one go. How to choose
- LED aquarium light, about 24 in long (opens Amazon in a new tab)Match the light to the tank length. Basic LEDs grow easy plants. How to choose
Food and extras for cherry barbs
- Micro pellets or flakes for small fish (opens Amazon in a new tab)Small enough for tetras, rasboras and other nano fish.

Water parameters
Keep them at 23–27 °C (73–81 °F), pH 6.0–7.5 and roughly 4–15 dGH. Farm-bred fish cope with most tap water, but soft, slightly acidic water brings out the deepest red. Change part of the water every week and avoid sudden swings.

Feeding
In the wild they pick at algae, detritus and tiny invertebrates. Use a quality small flake or micro pellet with some plant content as the staple. Add frozen or live daphnia, brine shrimp and bloodworm a few times a week to boost color.
Behavior
Peaceful and a little shy, they spend most of their time in the middle and lower water among plants. Males chase each other and display to females, but this rarely leads to damage. Good tank mates are small tetras, rasboras, corydoras, otocinclus and peaceful livebearers. Avoid boisterous barbs and fish large enough to bully them.
Breeding
Males are slimmer and bright red; females are rounder and tan-brown with the same dark side stripe. They scatter eggs among fine plants or moss, give no care and will eat any eggs they find. Spawn a pair in a separate dim tank with mesh, marbles or java moss on the bottom at about 27 °C (80 °F), then remove the adults. Eggs hatch in 1–2 days; feed infusoria first, then baby brine shrimp.
Tips from experienced keepers
- Keep about two females for every male so no single female gets chased too much.
- Dense plants and floating cover make them bolder and much redder.
- They eat baby shrimp, and a few individuals pick at adult cherry shrimp. Amano shrimp are usually safe.
- They are one of the safest barbs for a calm community. Do not mix them with fin-nipping tiger barbs.
Frequently asked questions
How many cherry barbs should be kept together?
Keep at least six. A group with more females than males, about two females per male, spreads out the chasing and makes the fish less shy.
Can cherry barbs live with shrimp?
Usually, with some care. They will eat baby shrimp and some may harass adult cherry shrimp, so give the shrimp lots of moss and plants. Larger amano shrimp are generally safe.
Can cherry barbs live with a betta?
Often yes, in a planted tank of 15 gallons (57 L) or more, because cherry barbs do not usually nip fins. The bigger risk is the betta: some chase red fish, so watch closely and have a backup tank ready.
