Emerald Eye Rasbora (Brevibora dorsiocellata)
 
The Emerald Eye Rasbora is a small, peaceful schooling fish named for the bright metallic green spot in its eye. Their slender bodies and shimmering silver-gold sheen make them a beautiful, subtle addition to planted aquariums. Active but gentle, they’re ideal for community tanks and do best in large groups where their natural schooling behaviour really shows.
