Whether you keep a planted tank, a reef, a betta, shrimp, cichlids, or a classic freshwater community, Aquarium Harmony turns scattered notes and guesswork into one clear answer: what does my aquarium need today?

Aquarium Harmony reads your real stock: preferred water ranges, group-size suggestions, and compatibility notes - turned into friendly insights, not alarms.
