Planned future direction
Tank Mates
Tank Mates is a planned animal and feeding notes concept for tracking livestock, food details, and reference care notes for each tank. Placement is TBD, and it is not live in the current app.
Future wording should stay descriptive: reference care notes, usual observed ranges, and records you enter. It should not imply diagnosis, treatment, product recommendations, or guaranteed care outcomes.
Planned does not mean live
Tank! Plus, Tank! Journalist, the Dosing Calculator, Lighting Profiles, Algae Watch, and Tank Mates should be read as plan or feature direction until an app version explicitly makes them available. Dosing Products remain current local records. Ad-free is a plan benefit direction, not a separate purchase. Tank! features are for recordkeeping and routine awareness, not diagnosis, treatment, product recommendations, or safety guarantees.
