Chinese Sleeper
Perccottus glenii
Chinese sleeper (Perccottus glenii) is a small, hardy goby-like freshwater fish native to East Asia and widely introduced elsewhere. It favors still or slow waters and is often associated with dense aquatic vegetation and soft bottoms.
Identification points
- Short, thick body with a large head and a blunt, wide mouth
- Two dorsal fins close together, with the front fin short and spiny
- Usually mottled brown to olive with dark blotches and banded fins
Habitat
Shallow, slow-moving or stagnant freshwater habitats such as ponds, ditches, floodplain backwaters, marshes, and vegetated lake margins; tolerates low oxygen and turbid water.
Bait notes
Takes small natural baits such as worms, maggots, insect larvae, and tiny fish pieces; small soft plastics and micro-jigs can also work. It is not usually a targeted sport species and catches are often incidental.
Behavior
An ambush predator that sits among plants or debris and feeds on insect larvae, small crustaceans, tadpoles, and fish fry. It is tolerant of poor water conditions and can persist in isolated, warm, weedy waters.
Caution
Check local regulations: this invasive species may be restricted or prohibited from live transport and release in some regions. Handle carefully around spines and avoid moving it to new waters.
Fishing notes
Fish light tackle close to weed edges, snags, and shallow cover, using slow retrieves or near-bottom presentations. Tiny hooks and small floats are effective in very still water where the fish holds tight to cover.
