物种概述

Nothobranchiidae species Nothobranchius rachovii comes from 非洲. An annual-strategy killifish: in nature its pools vanish, so it lives fast and leaves eggs behind. It swims in mid-water. Adults reach 4.9–7.2 cm. Small groups with floating plants for cover. Soft water, live foods and a tight lid cover most of what this short-lived jewel asks. Maintain 22–25 °C at pH 6–7.2. Water quality and diet matter more than décor.
