Aquarium Industry Statistics: Market Size, Growth & Consumer Trends
FishyHub cannot put a dollar size on the US aquarium industry, but its 2026 marketplace data shows clearly where it is growing and what consumers want. Activity is rising in every freshwater and saltwater livestock group on FishyHub's US marketplace, buyer interest is strongest for halfmoon plakat bettas, and shoppers' searches lean toward bold, unusual animals: monster fish such as channa, gar and bichir, invertebrates such as crabs and snails, and pets beyond fish such as turtles and axolotls.
Key Findings
- FishyHub marketplace data shows activity rising across every freshwater and saltwater livestock group in the US in 2026.
- FishyHub data shows freshwater livestock holds the larger share of US listings, while saltwater covers a broad catalog of corals, reef fish and invertebrates.
- FishyHub data shows halfmoon plakat bettas draw very high buyer interest in the US, with demand ahead of supply.
- FishyHub data shows demand clearly outpaces supply for giant halfmoon plakat bettas in the US, while halfmoon betta demand and supply are balanced.
- FishyHub search data shows arowana, bichir, channa, flowerhorn, gar and oscar among the most searched terms, a sign of strong interest in large "monster" fish.
- FishyHub search data shows shoppers looking beyond fish, with crab, snail and turtle among the most searched terms and axolotl, isopod and vampire crab also drawing strong interest.
- FishyHub Feed data shows "Other Animals", which covers turtles, frogs, axolotls and similar pets, as the most featured category in Feed videos.
Market Size: What FishyHub Can and Cannot Say
Industry market-size figures usually combine livestock, equipment, food, services and retail sales from many sources. FishyHub does not report figures and cannot measure the whole US market, so this page does not estimate it. What a marketplace can show is the shape of the market: what is listed, what people look for, where interest concentrates and which way activity is moving.
On that measure, the US aquarium market looks wide. US merchants list livestock in nearly every group FishyHub tracks, from tetras and goldfish to seahorses and LPS corals. Freshwater holds the larger share of listings, but saltwater is not a token presence; it covers corals, reef fish and invertebrates in depth.
Growth: Rising Activity Across the Board
Momentum on FishyHub compares new listings and orders in the recent year with the year before. In the US, every livestock group is rising, with no group steady or cooling. That includes:
- budget community fish such as danios, rasboras, swordtails and tetras;
- centerpiece freshwater fish such as angelfish, discus and flowerhorn;
- collector fish such as black and jardini arowana;
- saltwater corals, clownfish, damselfish, dartfish and dwarf angelfish.
A caveat matters here. FishyHub's US marketplace is new, so part of this growth reflects merchants joining and listing for the first time. The finding is the breadth of growth, not its rate: interest is building in every corner of the hobby at once, rather than in a single trend.
Consumer Trend: The Betta Boom
Buyer interest (wishlists, likes and "my tank" saves) gives the clearest view of US consumer demand on FishyHub, and it centres on bettas.
| Betta variety | Buyer interest | Demand vs supply | Activity |
|---|---|---|---|
| Giant Halfmoon Plakat | Moderate | Demand clearly outpaces supply | Rising |
| Halfmoon | High | Balanced | Rising |
| Halfmoon Plakat | Very high | Demand ahead of supply | Rising |
Halfmoon plakats combine the short, sturdy fins of a fighting betta with the full spread of a halfmoon, so they are colourful but more active and less prone to fin damage than long-finned show bettas. That suits beginners as well as collectors. Giant halfmoon plakats have limited supply in the US, so even moderate interest outruns what is listed. Many of these fish are bred in Southeast Asia, and supply depends on imports and a growing community of US breeders.
Bettas suit how many Americans live now: they do well in a small heated tank on a desk or shelf, need no tankmates, and have personality. The betta's appeal to apartment dwellers and first-time keepers is one reason it remains a doorway into the hobby.
Consumer Trend: Monster Fish and Big Personalities
FishyHub search data, which combines the US and Singapore markets, shows strong interest in large, predatory and characterful fish. Among the most searched terms are arowana, bichir, channa, flowerhorn, gar and oscar, and snakehead, stingray, peacock bass and toman also attract searches. In the US, monster fishes as a group sit in the collector tier.
Readers in the US should note that channa (snakeheads) are restricted under federal and many state rules, so this search interest reflects the global audience as much as what US buyers can legally keep. Gar, bichir, oscar and arowana species that are legal in a given state are the realistic US options.
Consumer Trend: Beyond Fish
Some of the strongest signals are for animals that are not fish at all. Crab, snail and turtle are among the most searched terms, and axolotl, beetle, frog, hermit crab, isopod, opae ula and vampire crab also draw high search interest. On FishyHub Feed, the "Other Animals" category is the most featured in videos.
This points to a broader shift from "a fish tank" to "a small ecosystem". Paludariums with crabs, vivariums with isopods, and sealed shrimp jars with opae ula all fall into this trend, and they appeal to people who might never set up a conventional aquarium.
Consumer Trend: Small Tanks and Nano Fish
Searches for endler, pea puffer, rasbora, rice fish and shrimp point to continued interest in nano tanks, where small schooling fish and invertebrates are kept in planted setups. On the US supply side, shrimps have very high supply and sit in the entry-level price tier, which makes a shrimp tank one of the most affordable ways into the hobby.
Methodology
This page is based on FishyHub marketplace activity in the US over the period from October 2024 to October 2026. We looked at active listings, new listings over time, wishlists, likes and "my tank" saves, search terms and FishyHub Feed videos. All findings are reported as tiers and directions (for example "very high interest", "demand ahead of supply", "rising"), not as figures.
FishyHub does not estimate the size or value of the US aquarium industry, and its US market has no order history in this data. Buyer interest in the US is currently measured for bettas only. Search terms and Feed data combine the US and Singapore markets. Notes on legal restrictions are general guidance, not legal advice or a FishyHub finding.
