Description
Shoal & Stem is the freshwater aquarium journal hobbyists actually use.
Whether you're keeping your first betta or running a high-tech planted scape, Shoal & Stem helps you stay on top of your tanks — without spreadsheets.
SNAP, SCORE, AND LOG YOUR TANKS
• Scan test kits with your camera. The AI reads parameter pads in seconds — no more typing pH, ammonia, and nitrate by hand.
• Score your tank's health. Get an at-a-glance number across factors like stocking, water quality, equipment, maintenance, plant cover, and ecosystem maturity.
• Track water changes. Log volumes, get reminders, see how consistent you are.
• Photo journal. Document your scape over time with notes and dated photos — or snap a quick full-tank shot anytime, straight from the camera.
• Archive retired tanks. Break down a scape without losing it — archived tanks keep their full journal, photos, and history.
ASK FINN ANYTHING
Finn is your AI aquascaping companion — trained on aquarium care, plant biology, fish compatibility, water chemistry, and aquascaping technique. Ask anything from "why is my plant melting?" to "what fish can I add to my 20 gallon?"
PLAN YOUR STOCKING
The Stocking Calculator tells you if your tank is overstocked. Pick species, see compatibility, get a balanced bioload number, and let Finn weigh in on your plan.
