Lambchop / Espei rasbora tank mates

A 3.5 cm orange rasbora with a shoulder marking shaped like a lambchop cut. Very peaceful, schools tightly, and works in almost any soft-water community.

Common mistakeBuying five lambchop rasboras for a tank already packed with danios or tiger barbs is how the school disappears from view. They need roughly eight or more and calm company; active competitors steal food and the group fades to glass-hugging beige. Start the school first, then add quieter neighbours.
