The go-to place for
everything fish

Aquacellum starts with a species database, then adds a marketplace, auctions, and tank logs. It's in beta.

One place for the hobby

📚

Species database

500+ freshwater and saltwater species: fish, corals, inverts and plants. Care data is cross-checked against FishBase and WoRMS. Open the database

🛒

Marketplace

Buy and sell by card through Stripe. We hold the payment until the handoff or arrival is confirmed, then pay the seller. How it works

🔨

Auctions

Timed auctions online, and club auction nights with lots, paddles, a clerk and a checkout desk.

📓

Tank logs

Log your tanks. Logs are saved on your device first and sync to your account when you're signed in.

A fee on card sales. That's it.

No subscriptions. Our fee on card sales is the only way we make money.

Sellers pay 4% on card sales, 2% when selling at an event, and 0% on cash sales they record themselves. Club auction desk card sales are 3%. Buyers pay no platform fee, only card processing (about 2.9% + $0.30), shown as its own line at checkout. All fees

What we do with your data

🔑

Sign in

Sign in with email or Google, through Privy.

📱

Your device first

Tank logs are saved on your device first and sync to your account when you're signed in.

📍

No public location

Listings don't show a location. A pickup spot is shared only between the buyer and seller of that order.

📊

Product analytics

We use PostHog to see which features get used and what breaks.

💳

Payments by Stripe

Card payments run through Stripe. Sellers are paid through Stripe Connect, and Stripe handles seller identity verification during onboarding.
