The Chili rasbora, or Brigittae rasbora, are bright little additions to the fish tank. These little fish are bright red and grow to only 1/2 inch. We recommend a School of at least six. Like match nerds, these micro rasboras are happier in a school. These tiny guys are great in small fish tanks, planted aquariums and they get along with fancy shrimp and other gentle tank mates.
