Fast Aquatics vs Chewy

Chewy is the dominant online pet retailer ($10B+ revenue, mostly dry goods). Fast Aquatics is the aquatics-only multi-vendor marketplace - we carry the live fish, coral, and inverts Chewy doesn't ship and the named cultivars no general retailer indexes.

TL;DR Chewy's strength is dry goods and recurring auto-ship for tank supplies, food, and meds. Their live fish program is partnership-based (LiveAquaria via Petco) with limited cultivar depth. Fast Aquatics is the live-livestock specialist with multi-vendor cart, carrier-tracked Buyer Protection, and 1,500+ named cultivar pages.

When Fast Aquatics fits better

Live livestock with deep selection. Chewy ships some live fish through partner programs but the catalog is shallow. Fast Aquatics has 100+ saltwater fish, 100+ freshwater, 80+ coral, 47 anemones / inverts, 56 plants, plus pond.
Named cultivars + breeder direct. Want a Wyoming White Clown, Walt Disney Tenuis, Snakeskin Discus, L046 Zebra Pleco? Chewy's catalog won't have them. Fast Aquatics indexes them with originator credit.
Carrier-tracked DOA mediation. Live livestock has different DOA protocols than dry goods. Fast Aquatics built the category-based photo-evidence DOA flow specifically for live aquatics.
Care library next to checkout. Each species and cultivar page on Fast Aquatics has a 500+ word care guide. Chewy's product pages are sales copy, not husbandry depth.

When Chewy fits better

Auto-ship for dry goods. If you've already got Hikari Marine S on Chewy auto-ship, don't break it. Fast Aquatics is additive on the livestock + cultivar side.
Pet meds and prescription items. Chewy's pharmacy is a different vertical entirely.
Cross-pet shopping. One Chewy cart for your dog, cat, AND fish supplies. Fast Aquatics is aquatics-only.

Frequently asked questions

Does Chewy sell live aquarium fish?

Chewy ships some live fish through partner programs - typically common community freshwater and a small saltwater selection. For specialty livestock, named cultivars, captive-bred marine fish, or designer strains, the catalog depth isn't there. Fast Aquatics is the marketplace specialist for live aquatics.

Is Chewy or Fast Aquatics better for aquarium supplies?

Chewy wins on dry-goods auto-ship and pet pharmacy. Fast Aquatics wins on live livestock, named cultivars, breeder-direct sourcing, and care content. Many hobbyists use both - dry goods on Chewy, livestock + specialty on Fast Aquatics.

Where can I buy specialty corals online?

Fast Aquatics aggregates direct-from-breeder coral inventory: SPS, LPS, soft, and named cultivars from World Wide Corals, Battle Corals, Tidal Gardens, JF Concepts, Cherry Corals, Top Shelf, and 50+ more vendors. Chewy doesn't compete in this niche.
