FishPotter — Your Complete Fish Keeping Guide

FishPotter is free, so the break-even is time saved and fish lives saved. A new aquarist typically spends 3–6 hours researching their first tank across YouTube, Reddit, and forum threads — a one-stop guide with integrated compatibility charts cuts that to 1–2 hours ($60–$180 in time value at a $30/hr reference rate) for $0. The bigger payoff is the avoided mistake: buying a wrong-mix community that attacks itself usually costs $40–$150 in lost fish and often a second equipment purchase, so preventing even one bad stocking decision is worth more than an annual subscription to a paid app. Advanced aquarists managing planted reefs should keep SeriouslyFish and AquariumScience bookmarked for deep science; FishPotter is the starting-point layer, not the end-state reference.
