Tetra Statistics: Most Popular Species & Aquarium Trends
Tetras are one of the most heavily listed small fish on FishyHub in the US. They have very high supply - higher than the small community fish group as a whole - sit in the entry-level / budget price tier with a wide spread between species, and listing activity is rising. "Tetra" is among the most searched terms on the marketplace.
Key Findings
- FishyHub marketplace data shows tetras have very high supply in the US, more than the small community fish group overall, which has moderate supply.
- FishyHub data shows tetras sit in the entry-level / budget price tier in the US, alongside danios, rasboras, swordtails and other small community fish.
- FishyHub data shows US tetra prices have a wide spread between species.
- FishyHub data shows tetra listing activity in the US is rising, as it is across small community fish.
- FishyHub data shows rasboras in the US have a very wide price spread, wider than tetras, driven by rare nano species.
- FishyHub search data shows "tetra" is among the terms shoppers search for most often, with "neon tetra" also searched.
- FishyHub's US marketplace is new and has no tetra order history yet, so popularity is read from listings, momentum and searches.
How Tetras Compare With Other Community Fish
Tetras are the backbone of the American community tank, and the listing data shows it.
| Fish | Supply | Price tier | Price spread |
|---|---|---|---|
| Danio | High | Entry-level / budget | Moderate |
| Molly | Moderate | Entry-level / budget | Narrow |
| Platy | Moderate | Entry-level / budget | Moderate |
| Rasbora | High | Entry-level / budget | Very wide |
| Swordtail | High | Entry-level / budget | Narrow |
| Tetra | Very high | Entry-level / budget | Wide |
Livebearers such as mollies and swordtails have narrow price spreads because most are farm-bred in standard colors. Tetras have a wider spread because the category runs from mass-farmed neons to wild-caught specialist species.
The Tetra Species US Keepers Choose
FishyHub lists tetras as one category, so its data covers tetras as a whole and does not rank species. These are the species most often seen in US stores and online, grouped by type and listed alphabetically:
Everyday schooling tetras
- Black neon tetra
- Black skirt tetra (including fluorescent and long-fin forms)
- Cardinal tetra
- Glowlight tetra
- Neon tetra
- Rummy-nose tetra
- Serpae tetra
Nano tetras for planted tanks
- Ember tetra
- Green neon tetra
- Lemon tetra
Larger and showier tetras
- Bloodfin tetra
- Buenos Aires tetra
- Congo tetra
- Diamond tetra
- Emperor tetra
On FishyHub, "tetra" sits in the very high search tier, while "neon tetra" and "congo" are limited-tier searches. Shoppers mostly browse tetras broadly, then pick species once they see what is listed.
Tetra Prices in the US
Tetras sit in the entry-level / budget tier in USD terms on FishyHub, with a wide spread. The main drivers:
- Farm-bred vs wild-caught. Neons, black skirts and serpaes are bred in large numbers, much of it on Florida and Asian fish farms, and are the cheapest tetras. Cardinals and some nano species are often wild-collected from South American rivers, which adds cost.
- Size. Bigger species such as congos and emperors cost more per fish than nano tetras.
- Genetically modified and selected lines. Fluorescent tetras and long-fin forms sit above the standard fish.
- Group pricing. Tetras are sold for schools, and many sellers offer group listings that lower the cost per fish.
FishyHub does not yet report US price trends, so this page describes where tetras sit, not how their prices are moving.
Aquarium Trends Behind Tetras
FishyHub's US listings show activity rising across nearly every freshwater category, and small community fish are no exception: tetras, danios, rasboras, minnows, hatchetfish, mollies, platys and swordtails all show rising listings. A few trends from the hobby help explain why tetras keep their place:
- Planted and nano tanks. Small schooling tetras such as embers and green neons suit compact planted tanks, a style that has grown with aquascaping.
- Shrimp-and-tetra setups. Neocaridina shrimp also have high, rising supply on FishyHub in the US, and peaceful nano tetras are a common pairing.
- Biotope tanks. Keepers recreating South American blackwater streams use cardinals, rummy-noses and pencilfish with leaf litter and driftwood.
Buying and Shipping Tetras in the US
Tetras are sold in nearly every local fish store, which makes common species easy to pick up. Online sellers on FishyHub add specialist and wild-caught species and larger groups. Sellers deliver across the Midwest & Central, East Coast & Northeast, South & Southeast, West Coast & Mountain West, and Alaska, Hawaii & territories zones. In hobby practice, small fish ship by overnight courier in insulated boxes, with heat packs for northern winters, and remote destinations such as Alaska and Hawaii usually cost more.
Keeping Tetras in an American Home
Most tetras need a heater in US homes, especially from fall to spring. Keep them in groups, in a tank with plants and gentle flow, and add new fish in batches so the filter can catch up.
Methodology
This page is based on FishyHub marketplace activity in the US over the 2026-2027 period. We looked at tetra and other small community fish listings, listed prices and price spread, new listings over time, related shrimp listings, and search terms. Findings are reported as tiers and directions, not figures.
The US marketplace is new: there is no US tetra order history, buyer-interest tier or price-trend data yet. FishyHub lists tetras as one category, so it does not rank species; the species guide draws on hobby knowledge and search terms. FishyHub does not report state-by-state data, and search terms combine the US and Singapore markets. The data does not measure how many Americans keep tetras.
