FISH — Aquarium Care

Clear care for thriving tanks

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

Know what your aquarium needs next—and why. Track water, livestock, growth, compatibility, symptoms and maintenance with calm, explainable guidance. FISH turns a few practical details about your aquarium into a clear care plan. Add your tank, filter and livestock, then log water tests and maintenance when you have them. FISH shows what needs attention, what can wait, and which facts changed the result. CARE THAT EXPLAINS ITSELF • A health score with critical warnings separated from planning estimates • Water-change timing and percentage, capped at 50%, with the reasons shown • Tank-specific water parameters for freshwater and marine aquariums • Measured trend charts that never disguise forecasts as test data • Filter capacity, turnover and service history included in the plan • Reminders that stay on your device LIVESTOCK THROUGH THE FULL LIFE CYCLE • 120 curated freshwater, coldwater and marine profiles with original portraits • Adult size, care ranges, grouping, feeding and sources • Growth-aware stocking estimates for juvenile fish • Adult stocking risk before today’s small fish outgrow the tank • Compatibility, group-size and water-range warnings • Stocking simulation and suitable-fish recommendations HELP WHEN A FISH LOOKS UNWELL • Choose visible symptoms without guessing a diagnosis • Immediate checks for water, oxygen and recent changes • Clear escalation when qualified aquatic help is appropriate • Safety guidance is always available and never paywalled FISH+ adds unlimited tanks, live-plant modeling, detailed 30-day forecasts, multi-species simulations, ranked recommendations, export and an optional AI advisor limited to three requests per day. Every AI request shows which tank facts will be sent. AI never overrides measured emergency warnings and is not a diagnosis or medication service. Your aquarium journal stays on your device. FISH has no account, ads or cross-app tracking. FISH provides husbandry planning information, not veterinary diagnosis.
