Occurs in cold, clear and fast-flowing water of small stream to medium-sized rivers as well as on gravel or rocky shores of cold lakes and in slightly brackish waters along eastern coast of Baltic coast (Ref. 59043). Feeds on small bottom invertebrates, mainly insects, crustaceans. Pink to yellow eggs are found in clumps attached to undersides of large stones (Ref. 41678). Contrary to statements in older literature, eggs and larvae of fishes are not a common food item (Ref. 45167).
在溪流 , 河川與湖泊中棲息於堅硬的底部 (在石頭下面), 極少在半鹹淡的沿岸水域。 吃小的底棲無脊椎動物, 主要地昆蟲，甲殼動物。 和陳述相反，在較舊的文獻中，卵與魚的仔魚不是一個普遍腳項目。 (參考文獻 45167) 粉紅色到黃色的卵聚集成叢依附於大石頭的下面。 (參考文獻 41678)

Spawns once a year for several years in low productivity streams, but exhibits multiple spawning within a season in high productivity environments (Ref. 40290, 40754). Male protects several batches of eggs--deposited below a stone--for about 3 weeks. Larvae are not guarded and may occasionally been eaten (Ref. 45166).
