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.
