Aquarium

Akwarium is an app for anyone keeping freshwater fish who wants to do it right.

CHECK WHICH FISH GET ALONG

Before you buy a new fish, check it against your virtual tank's current stock.

The app warns you about temperament conflicts, mismatched water parameters,

overstocking, and shoal sizes that are too small for schooling species.

TRACK WATER PARAMETERS

Log pH, temperature, ammonia, nitrite, and nitrate for each tank. See trends

over time and get reminders for overdue tests and water changes — tailored

to the tank, not blind timers.

SPECIES DATABASE

Browse freshwater fish species with their tank, water parameter, temperament,

and diet requirements. Data cross-checked against Seriously Fish, Fishbase,

and AqAdvisor.

TANK PROFILES

Run one tank for free, or go Premium to track as many as you like.
