The Most Engaging Aquarium Fish on Social Media: FishyHub Data
On FishyHub, the aquarium fish that draw the most engagement from US users are bettas: halfmoon plakat bettas collect the most likes, wishlists and "my tank" saves of any US-listed fish, halfmoons follow closely, and giant halfmoon plakats attract interest that clearly outruns supply. In FishyHub Feed, the platform's own video community, the most engaging content is unusual aquatic animals and scorpion fish. This is engagement inside FishyHub, not on other social networks.
Key Findings
- FishyHub data shows halfmoon plakat bettas have very high buyer interest from US users, the most engaged-with fish on the US marketplace.
- FishyHub data shows halfmoon bettas have high buyer interest in the US, and giant halfmoon plakat bettas moderate interest.
- FishyHub data shows demand clearly outpaces supply for giant halfmoon plakat bettas in the US, and demand is ahead of supply for halfmoon plakats.
- On FishyHub in the US, halfmoon plakat bettas sit in the mid-range price tier with a narrow price spread, while halfmoons and giant halfmoon plakats are upper mid-range.
- FishyHub data shows US listings of all three betta varieties are rising.
- FishyHub Feed data shows the Other Animals category is the most featured in Feed videos, with scorpion fish the fish group that registers most.
- FishyHub's US engagement signal is concentrated in bettas; other US categories do not yet register enough likes, wishlists and saves to tier.
How We Measure Engagement
"Social media engagement" usually means likes, shares and comments on public networks. FishyHub cannot see those. What it can see is engagement inside its own platform, in two places:
- Marketplace engagement. When a user likes a listing, adds it to a wishlist, or saves it to "my tank", that is a signal of interest. FishyHub combines these into a buyer interest tier for each category.
- FishyHub Feed. Feed is FishyHub's in-app community where members post short videos of their aquariums. Videos can be linked to a category, which shows what members choose to share.
Neither is Instagram, TikTok, YouTube or Facebook. Both are a useful proxy, though, because the people engaging are fishkeepers and shoppers rather than casual scrollers.
Bettas Lead US Engagement
The US marketplace on FishyHub is still young, and its interest signal currently registers only for bettas. Within that, the picture is clear:
| Betta variety | US buyer interest | Demand against supply | US price tier |
|---|---|---|---|
| Giant halfmoon plakat | Moderate | Demand clearly outpaces supply | Upper mid-range |
| Halfmoon | High | Balanced | Upper mid-range |
| Halfmoon plakat | Very high | Demand ahead of supply | Mid-range |
Why halfmoon plakats engage so strongly
Halfmoon plakats combine the short, sturdy fins of the fighting-fish plakat with the full, even spread of a show halfmoon. They are active, flare readily, and come in a huge palette of colors and patterns, including koi, nemo and solid metallics. For a US buyer, that adds up to a fish with personality that also looks good in a listing photo. A mid-range price and a narrow spread make it an approachable purchase, which turns likes into wishlists.
Why halfmoons stay close behind
The classic halfmoon, with its long, flowing tail that opens into a half circle when it flares, is the image most people have of a show betta. Its engagement is high, and US supply keeps pace with it, so demand and supply are balanced.
Why giant halfmoon plakats are scarce
Giant plakats grow far larger than standard bettas, which makes them striking on camera and in person. They take longer to raise and fewer breeders produce them, so US supply is limited. Interest is moderate, but because listings are so few, it clearly outruns what is available. Buyers who like a giant plakat on FishyHub often need to act quickly.
Why bettas suit online engagement
Every betta is an individual. Unlike a school of tetras, a single betta in a clear photo is exactly what a buyer will receive, and two fish of the same variety can look quite different. That encourages users to like and save specific fish while they compare, which is what FishyHub's engagement signal measures.
What Feed Members Share
FishyHub Feed tells a different story from the marketplace. The Other Animals category, aquatic pets outside the main fish groups, appears in Feed videos far more than anything else. Among fish, scorpion fish are the group that registers.
The difference is instructive. Marketplace engagement favours fish people intend to buy; Feed engagement favours the surprising and the dramatic. On FishyHub's US listings, Other Animals are mid-range with a very wide price spread, and scorpion fish are collector / premium with limited supply. Both are rising in US listings.
US Context
Bettas are well suited to American homes: they live happily in a modest heated aquarium, need no companions, and ship well by overnight courier when packed with care. Their popularity on FishyHub matches their long-standing place in US fishkeeping, from first-time keepers to breeders who show fish. Delivery reaches all five zones (Midwest & Central, East Coast & Northeast, South & Southeast, West Coast & Mountain West, and Alaska, Hawaii & territories), though bettas need a heat pack in winter shipments to colder zones. Shipping advice here is general hobby knowledge.
Methodology
This page is based on FishyHub marketplace activity over the period from October 2024 to October 2026. We looked at likes, wishlists and "my tank" saves on US listings (combined as buyer interest), demand relative to listings, listed prices and spread, how US listings are moving, and FishyHub Feed videos and their linked categories. All findings are reported as tiers and directions, not as figures.
"Social media" on this page means FishyHub's own platform: marketplace engagement and FishyHub Feed. FishyHub has no data on Instagram, TikTok, YouTube or other networks. Feed data is reported across all markets together. US buyer interest in this data registers only for betta categories, and the US market has no order history yet.
