What Fishori is, in plain English
Pick two freshwater fish. We tell you whether the pair is worth setting up, what the worst case looks like, and why. The verdict is conservative on purpose. Adult sizes, mouth gap, temperament, shared temperature window, shared pH window. Sources cited on every profile.
People mostly check Guppy vs Neon Tetra, Betta vs Tiger Barb, and Angelfish vs Neon Tetra. Every result explains the reasoning. No black-box score.
The full fish list has minimum tank sizes, schooling requirements, and the species we’d steer beginners away from. The tank builder runs the same checks across a whole stocking list, not just two fish at a time.
Not sure where to start? Beginner fish guide, peaceful community fish, and schooling fish cover the most common first-tank decisions. Planning by tank size: 60L · 100L · 200L. Browse all guides or all tank sizes.
