Both Danios and Rasboras are schooling fish, thriving when kept in groups of six or more. Danios, such as the Zebra Danio and Leopard Danio and Rasboras, such as the Harlequin Rasboras, are known for their fast swimming shoaling patterns. An interesting fact about Danios is their significant role in scientific research, especially the Zebra Danio, which is widely used in genetic and developmental biology studies due to its transparent embryos and rapid development. Their ease of care create a lively and visually appealing aquarium that can be enjoyed by both novice and experienced Australian aquarists alike
