Species Overview
巴拉金梭鱼
The great barracuda is a fearsome-looking predator found in tropical and subtropical oceans. With its torpedo-shaped body, pronounced underbite, and fang-like teeth, it can strike prey at speeds exceeding 58 km/h.
Plecostomus
The common pleco is a large armored catfish native to South America. Often purchased as an algae eater, it can outgrow most home aquariums. Its sucker-like mouth allows it to rasp algae from surfaces and anchor itself in fast-flowing currents.
