Species overview
Tetraodontidae species Dichotomyctere nigroviridis comes from 印度尼西亚. A personality with fins: it recognises keepers, patrols territory and investigates everything. It lives on the bottom. Adults reach 12.8–18.7 cm. One per tank is the safe rule. Plan around the beak: shelly foods weekly, heavy filtration, and few if any neighbours. Maintain 24–28 °C at pH 7.5–8.5. A solid choice for a well-planned community tank.
