The red axelrodi rasbora, named after Heiko Bleher's nemesis Herbert Axelrod, is also called the neon red rasbora. Neon red rasboras make a beautiful school in a small aquarium and stay small. Flake food is fine; pellets may be too large.

Care Guide
Tank setup: Give them dense plants, floating plants, a dark substrate and gentle filtration (a sponge filter is ideal, since they are small enough to be pulled into strong intakes). Soft, slightly acidic water brings out their best color.
Feeding: Feed crushed flake or micro pellets once or twice a day, only as much as they eat in a couple of minutes. They also enjoy frozen brine shrimp.
Tankmates: Keep them with other tiny, peaceful fish such as other micro rasboras, small tetras, pygmy corydoras, otocinclus and dwarf shrimp. Avoid large or boisterous fish, which can eat or stress them.
Good to know: Micro rasboras show their best color and natural schooling behavior in larger groups and well-planted tanks.
