Aquarium Statistics 2026: Fishkeeping, Ownership, Spending & Trends
FishyHub's US marketplace shows an aquarium hobby that is expanding on every front in 2026: new listings are rising in every freshwater and marine group FishyHub tracks, and freshwater livestock makes up the larger share of what is for sale. FishyHub cannot count how many Americans keep fish or what households spend in total, but its listings show where the money goes: most community fish sit in the entry-level price tier, while marine centerpieces, arowana and flowerhorn sit in the collector tier.
Key Findings
- FishyHub data shows activity in the US is rising across every livestock group it tracks, freshwater and marine alike, as new listings grow year on year.
- FishyHub data shows freshwater livestock holds the larger share of US listings, with marine livestock the smaller share.
- FishyHub data shows barbs, catfish, discus, goldfish, guppies, plecos, shrimp and tetras are among the most widely listed freshwater livestock in the US.
- FishyHub's US listings place most small community fish, including danios, guppies, mollies, platies, rasboras, swordtails and tetras, in the entry-level price tier.
- FishyHub data shows the US collector tier is dominated by marine fish such as tangs, dwarf and large angelfish, seahorses and eels, alongside arowana, flowerhorn and monster fish.
- FishyHub data shows LPS, SPS and polyp corals have very high supply in the US, with LPS corals listed in the collector tier.
- FishyHub data shows halfmoon plakat bettas draw very high buyer interest from US users, and demand for giant halfmoon plakats clearly outpaces supply.
Fishkeeping in the US: Freshwater First, Reef Close Behind
Freshwater fish hold the larger share of FishyHub's US listings, which matches how most American hobbyists start: a heated tropical tank with community fish, a betta in a desk tank, or goldfish in a pond. Freshwater tanks run on treated tap water, cost less to equip, and forgive the mistakes beginners make.
The marine side is smaller in share but unusually deep. FishyHub's US listings cover clownfish, gobies, wrasses, tangs, butterflyfish, anthias, dottybacks, dragonets, seahorses and many more marine fish groups, plus a broad coral and invertebrate selection. LPS, SPS and polyp corals all have very high supply. That breadth reflects the US reef scene: a large community of hobbyists who frag (cut and grow) corals at home and trade them, so coral supply is not limited to imports.
Ownership: What the Marketplace Can and Cannot Tell You
FishyHub is a marketplace, not a household survey. It does not measure how many people keep fish, how many tanks are in American homes, or what share of households own an aquarium. What it can show is the shape of the hobby among people who buy and sell livestock online:
- which kinds of fish are widely listed and which are scarce;
- which price tier each group sits in;
- where buyer interest is concentrated;
- whether activity is growing or slowing.
Read the findings on this page as a picture of the market, not a head count.
Spending: Where the Money Sits
FishyHub groups listed prices into tiers. Here is where common US livestock falls, grouped and listed alphabetically within each tier:
| Price tier | Examples on FishyHub (US) |
|---|---|
| Entry-level / budget | Corydoras, danios, guppies, loaches, mollies, Neocaridina shrimp, platies, rasboras, snails, swordtails, tetras |
| Mid-range | African and American cichlids, angelfish, bettas, blennies, damselfish, freshwater puffers, gobies, koi |
| Upper mid-range | Anemones, clownfish, discus, halfmoon bettas, plecos, SPS and soft corals, wrasses |
| Collector / premium | Arowana, dwarf and large marine angelfish, eels, flowerhorn, LPS corals, seahorses, tangs |
Two things stand out. First, a freshwater community tank can be stocked almost entirely from the entry-level tier, which keeps the hobby open to new keepers. Second, spending climbs steeply on the marine side, where many fish groups sit in the upper mid-range or collector tier.
What drives price
- Ease of breeding. Livebearers, tetras and cherry shrimp are farm-bred in huge numbers in Florida and across Asia, so they stay cheap.
- Wild collection. Many marine fish are still collected from reefs rather than bred, and shipping them alive is costly. Tangs, angelfish and seahorses carry those costs.
- Size and age. Arowana, flowerhorn and large monster fish take years to grow and need big tanks, so sellers price them as long-term investments.
- Variety and grade. Groups with a very wide price spread, such as clownfish, goldfish, flowerhorn and plecos, cover everything from common forms to designer or rare variants.
Trends for 2026
Because FishyHub's US marketplace is new, every livestock group shows rising activity against the year before. The more useful signals are where interest and supply concentrate:
- Bettas are the clearest interest story. Halfmoon plakats draw very high buyer interest and demand runs ahead of supply. Giant halfmoon plakats are scarcer, and demand clearly outpaces what is listed.
- Reef keeping is broad. Coral supply is very high across LPS, SPS and polyps, and marine fish listings span both beginner fish and collector species.
- Cichlids are a deep category. American cichlids, discus and other cichlids all have very high supply, reflecting long-running US interest in big, characterful fish.
- Oddballs attract searches. FishyHub search data shows shoppers looking for axolotls, isopods, pea puffers, rice fish, vampire crabs and wild bettas alongside everyday species.
The Delivery Zones
FishyHub organizes US delivery into five zones: Midwest & Central; East Coast & Northeast; South & Southeast; West Coast & Mountain West; and Alaska, Hawaii & territories. FishyHub does not report sales or buyer counts by state or zone.
From hobby experience, live fish usually travel by overnight courier in insulated boxes, with heat packs in winter and cold packs in summer. Longer distances, extreme weather and remote destinations such as Alaska, Hawaii and the territories make shipping costlier and riskier, which is one reason many keepers combine online orders with trips to a local fish store.
Methodology
This page draws on FishyHub marketplace activity in the US over the period from October 2024 to October 2026: active livestock listings, listed prices and how widely they range, buyer interest from FishyHub users (wishlists, likes and "my tank" saves), new listings over time, and search terms. All findings are reported as tiers and directions, such as "entry-level", "very high supply" or "rising", rather than figures.
The US marketplace is new, so it has no order history in this data, and buyer interest is only reported where there is enough activity (currently bettas). Search terms combine the US and Singapore markets. FishyHub does not measure how many Americans own fish, household spending, or state-by-state activity; statements about ownership and shipping draw on general hobby knowledge.
Frequently Asked Questions
How many people in the US have an aquarium?
FishyHub cannot measure that, because it is a marketplace rather than a survey. Its data shows a growing US market, with listings rising in every livestock group in 2026.
Is freshwater or saltwater more popular in the US?
On FishyHub, freshwater livestock holds the larger share of US listings. Marine is smaller in share but very broad, with very high coral supply.
How much does it cost to stock an aquarium?
It depends on the fish. Most small community fish and shrimp sit in FishyHub's entry-level tier in the US, while many marine fish, arowana and flowerhorn sit in the collector tier.
What aquarium fish are trending in 2026?
On FishyHub, halfmoon and halfmoon plakat bettas draw strong buyer interest, and searches show growing curiosity about axolotls, isopods, pea puffers and wild bettas.
