Finlog: Aquarium Log & Tracker

New: the Nano Tank. Pick a lifelike betta, ryukin goldfish or neon tetra, feed it every day and watch it grow in 3D. Logging your real tank's feedings earns extra snacks.

Keep your aquarium healthy in a few taps a day. Log water tests, feeding and water changes, check a sick fish with AI, and ask aquarists worldwide. Then unwind in the Nano Tank and raise your own lifelike 3D fish.

◆ 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.

◆ Fish guide and tankmate check Pick from 66 species with 3D illustrations to fill in temperature, pH, size and lifespan. Finlog warns about risky tankmates, small schools, fin nippers and an overcrowded tank.

◆ Handy tools Water calculator (volume, water change, dose), tank cycling progress, salt bath and medicine timers, and days-together anniversaries.

◆ 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.

◆ The Nano Tank: raise a lifelike 3D fish A bonus tank in the Home tab, just for fun and separate from your records. Choose your first fish from three lifelike species: a Betta, a Ryukin goldfish and a Neon tetra, give it snacks every day and watch it grow little by little. When it grows up, an egg arrives and a second and third fish join (up to 3). Logging a feeding for your real tank earns snack rewards. Spin and zoom to watch from any angle while the plants and bubbles sway, or turn your phone sideways for a wide view. It never changes your real records. Free, with no ads in the Nano Tank.

◆ 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.

◆ Finlog Premium (one-time purchase) No ads, plenty of AI tank checks and instant AI answers on the board. No subscription.
