科: Cichlidae
阿卡西短鲷为慈鲷科鱼类，领域性强，用造景遮挡视线可显著降低冲突，原生分布于南美洲。聪明鱼，会重排造景、认得主人，也会惩罚光秃拥挤的缸。成体约 3.3–4.8 cm，一对占领一个领域，每对都要有可防守的洞穴，适宜水温 26–29 °C。过滤要强，石头要堆。
Apistogramma agassizii, a member of the family Cichlidae, is native to 南美洲. A thinking fish that rearranges décor and learns its keeper — and punishes bare, crowded tanks. It lives on the bottom. Adults reach 3.3–4.8 cm. A pair claims a territory; give each a defensible cave. Over-filter for its messy habits, aquascape with rock walls, and respect its claimed corner. Maintain 26–29 °C at pH 5–7. A rewarding species for the aquarist who reads before buying.
