Dwarf Emerald Rasbora
Emerald Dwarf Rasbora are a beautiful and diminutive addition to a nano planted aquarium!
They are similar to celestial pearl danios both in appearance and in behavior/care.
Peaceful and fairly cryptic, they will be less shy when kept in groups. They max out at a little over an inch and do best in tanks 10g+ (so you have room for a group!) They won't fight with other fish, but too active of tankmates will keep them hiding so it is recommended to avoid anything too boisterous.
