Finlog: Aquarium Diary

A few taps a day keep your aquarium healthy. Log feeding, water tests and water changes, keep a photo diary of your fish, check a sick fish with AI, and ask aquarists around the world when something looks off.

◆ Every tank in one place
Freshwater, planted, shrimp, betta, goldfish, cichlid, marine and reef tanks, and ponds. Add your fish, shrimp, snails, plants and corals, and see how many days each tank has been running.

◆ Water tests you can read at a glance
Temperature, pH, ammonia, nitrite, nitrate, GH, KH, TDS and salinity. Each value is colored against an ideal range for your tank type, and charts show the last 7, 30 or 90 days.

◆ Never miss feeding or a water change
Log today's feeding with one tap and keep your streak going. Reminders tell you when to feed and when a water change is due. Record water changes, filter cleaning, dosing, glass and substrate work with notes.

◆ A photo diary of your tank
Keep photos for each tank and look back at how it has grown since the day you set it up.

◆ AI tank check
Take a photo of a fish, algae or cloudy water. AI tells you what it sees, what it noticed and the first steps to take, using your latest water test. One free check a day. This is general information, not a veterinary diagnosis.

◆ Everyone's Tanks
Share a photo of your tank, send stamps to other tanks, join the weekly theme and see aquarists around the world on the map. No followers, no comments, no numbers to compare.

◆ Ask other aquarists
Ask about water, fish health, plants or gear. Aquarists around the world answer, and posts are translated into your language. If a genuine question gets no reply within a day, AI shares some pointers.

◆ A safe community
Everyone agrees to the community guidelines before joining. Every photo is checked by AI before it is shared, and you can report any post and block any user at any time.
