Rasbora Micro Emerald

The Micro Emerald Rasbora, also known as the Emerald Dwarf Rasbora, is a stunning nano fish prized for its iridescent emerald-green body, delicate blue striping, and peaceful nature. Small in size but rich in colour, this beautiful species is a favourite among aquascapers looking to add subtle elegance and movement to planted aquariums.

Native to Myanmar, the Micro Emerald Rasbora thrives in well-planted aquariums where its vibrant colours contrast beautifully against lush greenery and natural hardscape.
