Rasbora axelrodi — Cardinal Tetra (variant)

This Cardinal Tetra variant displays the characteristic vivid blue and red horizontal banding of the cardinal tetra lineage, often with an enhanced iridescent, diamond-like sheen across its scales. It inhabits soft, acidic blackwater rivers of South America. Like its close relatives, it is best kept in schools in well-planted, dimly lit aquariums.
