科: Callichthyidae
三线豹鼠为美鲶科鱼类，夜行性居多，白天安静潜伏，原生分布于南美洲。触须状的须子像手指一样阅读沙地，粗糙底砂会慢慢磨损它。成体约 4.6–6.7 cm，小型种可成对，大型种单养，适宜水温 22–26 °C。沉底饲料，关灯后再喂。
From the waters of 南美洲 comes Corydoras trilineatus, a member of the family Callichthyidae. A whiskered bottom resident whose day begins when the lights go off. It lives on the bottom. Adults reach 4.6–6.7 cm. Keep bottom stock light — they share one floor. Feed sinking foods after lights-out, keep the sand soft, and never let nitrate climb unnoticed. Maintain 22–26 °C at pH 6–8. A solid choice for a well-planned community tank.
