Occurs in swamps and flooded grounds with shallow, almost stagnant water, which may either be clear or loaded with sediments. A quiet fish which finds shelter among aquatic plant stocks or amidst tree roots. Its long dense branchiospines suggest microphagous and planktophagous feeding, possibly including small crustaceans (Ref. 35237). It possesses weak teeth, indicating that it is not a predator. Has never been spawned in the aquarium nor are there reports of any spawning in nature (Ref. 12251). May occur together with the following species: Hoplosternum littorale, Parauchenipterus galeatus, Chaetobranchus flavescens, Pterophyllum scalare, Heros efasciatus, Mesonauta guyanae, and Hypselecara temporalis.
用水淺又幾乎污濁的水出現於沼澤與被水淹沒的地面, 那可能不是是清澈的就是充滿沉澱物。 發現在水生的植物分枝之中的庇護所的一個安靜的魚或在樹根當中。 它的長密集的鰓刺意味著吃微生物與吃浮游生物食性, 可能地包括小型甲殼動物。 (參考文獻 35237) 它持有弱的齒,指出它不是一個掠食者。 從未被產卵於水族館中也不在在那裡任何被產卵在自然中的報告。 (參考文獻 12251) 可能出現伴隨著下列的種: Hoplosternum littorale ， 副項鰭鯰〔Parauchenipterus galeatus〕 , 巴西鬃鰓魚〔Chaetobranchus flavescens〕 ,Pterophyllum scalare,英雄 efasciatus,Mesonauta guyanae, 與 Hypselecara temporalis
