Aquarium Fish Price Index 2026: What Pet Fish Really Cost
Most aquarium fish sold in the US in 2026 cost less than their reputation suggests. On FishyHub, everyday community fish such as tetras, rasboras, guppies, platies and corydoras sit in the entry-level / budget price tier, and centerpiece fish like bettas, angelfish and goldfish sit in the mid-range. Prices climb into the upper mid-range for discus, show bettas and most reef fish, and into the collector tier for arowana, flowerhorn, large monster fish and showpiece marine species such as tangs, marine angelfish and seahorses.
Key Findings
- FishyHub's 2026 US price index places most small community fish, including danios, mollies, platies, rasboras, swordtails and tetras, in the entry-level / budget price tier.
- FishyHub data shows bettas, angelfish, goldfish, koi and most cichlids sit in the mid-range price tier in the US.
- FishyHub data shows discus, halfmoon and giant halfmoon plakat bettas, plecos and silver arowana sit in the upper mid-range price tier in the US.
- On FishyHub, arowana, flowerhorn, datnoids and the monster fish category as a whole sit in the collector / premium tier in the US.
- FishyHub data shows marine fish are priced above freshwater fish in the US: most reef fish families are upper mid-range, and tangs, dwarf and large marine angelfish, seahorses, eels, groupers, sharks and rays are collector tier.
- FishyHub data shows goldfish, flowerhorn, plecos, freshwater puffers and clownfish have a very wide price spread between varieties in the US, so the variety matters more than the species name.
- FishyHub data shows freshwater livestock holds the larger share of US listings, and listing activity is rising in every category FishyHub tracks as the US marketplace grows.
How to Read This Index
FishyHub does not publish dollar averages. Instead, each category is placed in a price tier based on its typical listed price in USD on the US marketplace, relative to everything else for sale:
- Entry-level / budget - the least expensive fish and invertebrates on the marketplace.
- Mid-range - the middle of the market, where most popular single-species purchases sit.
- Upper mid-range - line-bred, show-grade or harder-to-breed fish.
- Collector / premium - large, rare or prestige species.
The index also shows the price spread for each group: how far prices range between varieties. A narrow spread means most sellers price comparable fish alike. A very wide spread means the label alone tells you little, and the exact strain, size or grade sets the price.

Surprises in the index
A few results run against expectations. Oscars and knifefish sit in the entry-level / budget tier in the US, even though they grow into large fish. That is because they are usually sold as small juveniles, and the real cost of these fish comes later, in a large tank and filtration. Crowntail bettas are also entry-level, while halfmoon bettas of the same species sit in the upper mid-range. And clownfish, often thought of as a starter marine fish, sit in the upper mid-range with a very wide spread, because designer clownfish lines are priced far above standard ocellaris.
Why Some Fish Cost So Much More
How easily the fish breeds
Livebearers such as guppies, mollies, platies and swordtails breed readily, and US fish farms, many of them in Florida, have produced them in volume for generations. Egg-scattering community fish such as danios, tetras and barbs are similar. High, steady supply keeps all of them in the budget tier.
Time to grow
Discus, large cichlids and arowana take a long time to reach a saleable size, and every month in a breeder's tank adds cost. Fish sold at adult or near-adult size cost far more than juveniles of the same species.
Captive-bred or wild-caught
Most marine fish are still collected from the wild and shipped long distances, with losses along the way. Species that are hard to collect or keep alive in transit, such as seahorses and dwarf angelfish, land in the collector tier. Captive-bred marine fish are easier to keep but cost more to produce.
Line breeding and grade
Bettas, goldfish, flowerhorn and plecos all show wide or very wide price spreads because the same species can be sold as a pet-grade fish or as a selected show line. Color, finnage, head growth and rare patterns are what buyers pay for.
Legal and supply limits
Some prestige species are restricted in the US, so the arowana on offer are the varieties that can be sold legally. Limited supply of black and jardini arowana keeps them in the collector tier.
What Pet Fish Really Cost: The Extras
The fish is often not the largest part of the bill. A few costs to plan for, based on general hobby practice rather than FishyHub data:
- Shipping. Live fish travel by overnight courier in insulated boxes, with heat packs in winter and cold packs in summer. Shipping is usually charged per box, so buying several fish from one seller spreads the cost. FishyHub's delivery zones are Midwest & Central; East Coast & Northeast; South & Southeast; West Coast & Mountain West; and Alaska, Hawaii & territories. Distance from the seller matters, and the remote zone generally costs the most.
- Heating. Most tropical fish need a heater in a US home for much of the year, especially in the Midwest, Northeast and Mountain West.
- Tank size. Budget juveniles such as oscars, plecos and silver arowana outgrow small tanks quickly.
- Local store or online. A local fish store lets you see the fish before buying and avoids shipping. Buying online gives access to specialist breeders and varieties a local store may not carry.
Which Way the Market Is Moving
The US marketplace is new, so FishyHub cannot yet report whether prices are rising or easing. What it does show is activity: new listings are rising across every freshwater and marine category tracked, from guppies and bettas to clownfish, damselfish and SPS corals. Freshwater fish make up the larger share of listings, with marine fish and corals the smaller but higher-priced share.
Methodology
This index is based on FishyHub marketplace activity in the US over the period from October 2024 to October 2026. We looked at active listings and their typical listed prices in USD, the spread of prices within each category, the balance of freshwater and marine listings, and new-listing activity over time. Each category is reported as a tier (entry-level / budget, mid-range, upper mid-range, collector / premium) rather than as a price figure.
The US market has no order history in this data, so the index reflects what sellers list fish for, not what buyers paid, and FishyHub does not report US price direction yet. Shipping costs by zone and state-level figures are not covered; shipping notes come from general hobby practice. The index covers fish sold through independent merchants on FishyHub, not the whole US aquarium trade.
