Behavior
They are nocturnal creatures and usually cruise during the twilight hours. They normally hunt live prey and will try any fish that fits into their mouths. Young clown knifefish usually school near water logs and plants for security, whereas more mature specimens usually become territorial and eventually become loners. These fish can also breath air to survive in stagnant waters and little oxygen. The clown knifefish prefers water around neutral pH and temperature ranging from 75 to 85 F.

Famous quotes containing the word behavior:
“... two men could be just alike in all their dispositions to verbal behavior under all possible sensory stimulations, and yet the meanings or ideas expressed in their identically triggered and identically sounding utterances could diverge radically, for the two men, in a wide range of cases.”
—Willard Van Orman Quine (b. 1908)
“No one is without Christianity, if we agree on what we mean by that word. It is every individual’s individual code of behavior by means of which he makes himself a better human being than his nature wants to be, if he followed his nature only. Whatever its symbol—cross or crescent or whatever—that symbol is man’s reminder of his duty inside the human race.”
—William Faulkner (1897–1962)
“To a first approximation, the intentional strategy consists of treating the object whose behavior you want to predict as a rational agent with beliefs and desires and other mental states exhibiting what Brentano and others call intentionality.”
—Daniel Clement Dennett (b. 1942)
