Tetras are among the most popular freshwater aquarium fish because of their color, schooling behavior and suitability for many planted and community tanks. FishyHub makes it easier to discover different Tetra species from multiple sellers in one marketplace.
Buying Tetras online gives hobbyists access to a broader range of species than may be available at a single local aquarium store.
Compare species, group sizes, seller availability and shipping options before choosing Tetras for your freshwater aquarium.
Popular Tetras in the aquarium hobby include:
Neon Tetras are one of the most recognizable small freshwater aquarium fish, known for their bright blue stripe and contrasting red coloration.
They are widely kept in planted and community aquariums where groups can create strong visual movement across the tank.
Cardinal Tetras resemble Neon Tetras but display a more extensive red stripe along the lower body.
Their intense blue and red coloration makes them especially popular in planted aquariums and darker aquascapes.
Rummy Nose Tetras are known for their bright red heads and distinctive black-and-white tail markings.
They are especially popular with hobbyists who enjoy coordinated schooling behavior in larger planted or community tanks.
Ember Tetras are small orange-red fish that work especially well in planted and nano-style aquariums.
Their compact size and warm coloration can create strong contrast against green plants and dark substrate.
Black Neon Tetras display a contrasting horizontal stripe pattern and are active schooling fish for community aquariums.
They can be a good option for hobbyists who want a classic Tetra body shape with a darker, more understated appearance.
Glowlight Tetras are named for the bright orange-red stripe that runs along the side of the body.
They are well suited to peaceful community aquariums and can look especially attractive under subdued planted-tank lighting.
Black Skirt Tetras are deeper-bodied than many smaller Tetra species and have distinctive dark vertical markings.
They are active community fish but may behave differently from smaller peaceful Tetras, so group size and tankmates should be considered carefully.
Serpae Tetras are colorful red-toned fish known for active behavior.
They can be more assertive than very peaceful Tetra species and may nip fins in unsuitable groups or community setups, so compatibility deserves additional attention.
Congo Tetras are larger than many commonly kept Tetras and are known for iridescent coloration and flowing fins.
Their adult size and activity level mean they require more swimming space than compact species such as Neon or Ember Tetras.
Many Tetras are social fish that are best kept with others of the same species.
Appropriate group size can improve natural behavior and create the schooling or shoaling displays that make Tetras so popular in freshwater aquariums.
Many Tetra species work well in peaceful freshwater community aquariums.
Suitable tankmates depend on the exact species, adult size and temperament, so a Neon Tetra community may be planned differently from one containing larger or more assertive Tetras.
Tetras are especially popular in planted aquariums because their schooling behavior and bright coloration complement aquatic plants and natural aquascapes.
Plants can provide visual cover and shaded areas while leaving open swimming space for active groups.
Some smaller Tetra species can be considered for appropriately sized nano aquariums, but small adult size does not automatically mean a fish needs little swimming space.
Consider group size, activity level and actual aquarium dimensions before selecting compact species such as Ember Tetras.
Tetras should be kept in a properly cycled freshwater aquarium with stable water conditions and suitable filtration.
A combination of open swimming space, plants and other visual structure can work well for many species.
Tetras come from a wide range of habitats and should not all be treated as requiring identical water conditions.
Stable aquarium conditions matched to the exact species are more important than applying one universal pH, hardness or temperature range to every Tetra.
Many Tetras can coexist with peaceful freshwater fish that share compatible water and space requirements.
Corydoras, Rasboras, small Gouramis and selected livebearers may be possible tankmates, but compatibility should always be checked by exact species.
Some Tetras can coexist with Bettas, but compatibility depends on both species and individual temperament.
Avoid especially nippy Tetra species with long-finned Bettas and provide enough space for each fish to establish comfortable areas.
Adult shrimp may coexist with some small Tetra species in planted aquariums.
Newly hatched shrimplets are small enough to be eaten by many fish, so dense plants and moss may improve survival but cannot eliminate predation.
Many commonly kept Tetras are omnivorous or opportunistic feeders and can accept appropriately sized prepared aquarium foods.
Quality flakes or micro-pellets can be supplemented with suitable frozen or other foods, depending on the exact species.
Food size should match the mouth size of the species, particularly for small Tetras such as Neon, Cardinal and Ember Tetras.
Avoid excessive feeding and remove persistent uneaten food to help maintain stable aquarium water quality.
Many Tetras can be suitable for newer aquarium keepers when the aquarium is properly cycled and their group requirements are understood.
Some species are more sensitive or more assertive than others, so choose based on the exact Tetra rather than assuming all members of the group have identical care.
Many Tetras reproduce by scattering eggs rather than providing parental care.
Breeding methods differ by species and may require separate conditioning, spawning and fry-rearing setups.
When comparing Tetras for sale, look for:
Newly shipped Tetras may experience stress from transport and changes in water conditions.
Prepare a stable, cycled aquarium in advance and follow an acclimation method appropriate to the seller's instructions and the species being introduced.
Tetra prices vary according to species, size, rarity, origin and seller.
Common schooling species and less commonly offered Tetras can differ substantially in price, so compare livestock condition, group quantity and seller terms as well as individual fish price.
FishyHub brings Tetra listings from aquarium stores, breeders and freshwater fish sellers together in one marketplace.
When comparing Tetras online, consider:
Shipping availability depends on the seller, destination, weather and livestock-shipping policy.
Review packaging, delivery timing and live-arrival terms before ordering, and prepare the aquarium before the fish are scheduled to arrive.
Yes. Aquarium stores, breeders and online fish sellers offer many Tetra species for delivery within the U.S., depending on seller coverage and livestock-shipping policies.
Neon, Cardinal, Rummy Nose, Ember, Black Neon, Glowlight and Black Skirt Tetras are among the most familiar aquarium species.
Many Tetras are social and benefit from being kept with others of their own species, although appropriate group size varies by species and tank setup.
Many species are excellent community fish, but some are more assertive or prone to fin nipping, so exact species compatibility should be checked.
Some combinations can work, but avoid aggressive or fin-nipping Tetras and consider the temperament of the individual Betta.
Some small Tetras can coexist with adult shrimp, but very young shrimplets may be eaten.
Both have bright blue and red coloration, but Cardinal Tetras generally show red extending farther along the lower body.
