Care caveats

notesTight-schooling indicator tetra; nose color fades fast when water quality or stability drops.
caveatKeep a group of 8 or more; rummynose are tight schoolers and stress visibly in small groups.
caveatSensitive to unstable water — a sudden loss of red nose color often signals ammonia, nitrite, or parameter swings.
caveatBest added to a mature, cycled tank with steady temperature and gentle, well-oxygenated flow.
caveatAvoid large or aggressive tankmates; rummynose are peaceful and will be outcompeted at feeding by boisterous species.
