@kr.aquatics: Galaxy rasboras (Celestial Pearl Danios) have a reputation for being shy, secretive fish, and sometimes that’s true. I’ve kept them before where I barely saw them, as they spent most of their time hiding in plants. But in this aquarium, they’re the complete opposite. They’re constantly out in the open and swim straight to the front whenever I walk past, expecting food. A big reason for that, in my opinion, is the addition of kubotai rasboras — a similar-sized species that’s naturally more active and confident. Fish constantly assess risk through movement. When they see other fish swimming calmly in open water, it acts as a safety signal and reduces perceived threat. If your galaxy rasboras — or other small schooling fish — spend most of their time hiding, adding a slightly more outgoing schooling species can make a noticeable difference. #galaxyrasbora #nanofish #aquarium #plantedaquarium #aquascape
