What Clarifish does for your tank
One companion for water, livestock and upkeep, from your first tank to the most demanding reef.
Your water tests, read and explained
Enter your values or snap a photo of your test strip, drop test or photometer. Clarifish interprets every parameter and tells you what to do.
Drifts caught before your fish feel them
The app tracks your water over time and warns you as soon as a value starts to slip.
Over 3,300 species
Illustrated profiles, compatibility between tankmates and with your water. The simulator shows you the effect of a newcomer before you buy.
Plants and algae
Plant profiles, plus a guide to understanding the algae that show up and what they say about your tank.
Upkeep at the right pace
Water changes, filter cleaning, feeding: a schedule matched to what actually lives in your tank, with reminders.
Every environment has its own rules
Freshwater, marine, brackish, garden pond, aquaterrarium for a turtle or axolotl, jellyfish kreisel: Clarifish adapts its thresholds and advice to your setup.
Marin, your onboard coach
An old sea dog turned fishkeeper. Ask your question out loud: he listens, answers you in his own voice and calls you shipmate.
“Cloudy water since yesterday? No need to panic, shipmate: we'll look into it together.”
Just starting out?
Answer 7 questions about your tastes, budget, time and space. Clarifish puts together a complete plan for you: species, plants, equipment, shopping list and an honest cost estimate.
No advice beats wrong advice.
Clarifish's thresholds and doses come from published veterinary and scientific sources. When data is missing, the app tells you instead of making something up.
