Fast Aquatics offers the lowest combined cost of any aquatic marketplace - $30/month Founder tier (free for first 100 vendors) + 12% take rate, dropping to 7% at the Enterprise tier. Wholesale orders are 6% across all tiers.
Most aquatic vendors selling online get hit by three cost layers: marketplace listing fees, transaction fees, and payment processor fees. Fast Aquatics charges only the first two and structures both to scale down as your volume grows.
The Fast Aquatics pricing model:
Compare to alternatives at the same shipping cost:
Fast Aquatics also negotiates aggregated FedEx + UPS rates for vendors via the marketplace shipping network. At 1,000+ packages/month aggregate volume across the platform (reached month 6-12), vendors get 25-35% off retail rates - a meaningful margin add on top of the lower take rate.
Yes - first 100 vendors pay $0 monthly subscription, with the 12% take rate kicking in only on completed sales. Free trial is 30 days for any tier you pick.
eBay's all-in cost on a $100 sale is ~18% ($12.90 final value fee + $0.30 + ~5% PayPal). Fast Aquatics's Founder tier is 12% for that same $100 - $6 cheaper before factoring in the $30/month subscription. Above ~$2,500 monthly GMV, the Pro tier (9%) becomes cheapest.
Whatever specific topic brought you here, four fundamentals govern long-term aquarium success: water quality, parameter stability, biological filtration, and species-appropriate husbandry. Skip any one and the others struggle to compensate.
Water quality: ammonia + nitrite at zero, nitrate under 30 ppm freshwater + 10 ppm reef. Test weekly with API or Salifert kits. Use our water parameter checker to score your readings against your tank type.
Parameter stability: stable wrong parameters beat fluctuating ideal parameters. Most fish tolerate a wide pH range if it's stable. Sudden swings of 0.4+ pH or 5+°F kill fish faster than chronic suboptimal values. Use temperature controllers (Inkbird) + automated dosing for consistency.
Biological filtration: the bacterial colony on your filter media + rock + substrate is the engine. Never replace all media at once. Use our filter turnover calculator to size correctly.
Species-appropriate husbandry: research adult size, territoriality, diet, and tankmate compatibility before purchase. Use our tank stocking calculator + compatibility guides.
How long does an aquarium take to set up? 4-6 weeks for full cycling + first stocking. Use our cycle ETA calculator + how long does cycling take.
What's the best aquarium for beginners? 20-gallon long. Big enough for parameter stability, small enough for budget + space. See beginner picks.
How often should I do water changes? 25-30% weekly. See water change frequency Q&A + water change calculator.
Why does my fish keep dying? 5 leading causes: uncycled tank, wrong species pairings, no quarantine, undersized tank, neglected water-change schedule. See full diagnosis.
