Rummy Nose Tetra tank mates
Rummy-nose tank mates belong in soft, stable Amazon-style water where the red noses stay red. Cardinals, cories, and calm dwarf cichlids fit; hard-water livebearers and cool communities fight the chemistry. Keep eight or more. If noses bleach, fix the tank before you add another species to 'liven it up.'
Common mistakeAdding a rummy-nose school to a tank under three months old is how keepers invent permanently pale noses and 'failed colour' returns. They signal water problems fast. Only add them to a fully cycled, established tank with a real school — not as a cycling decoration.
