It lives in a tropical climate in water with a 5.8–8.0 pH, a water hardness of 2–30 dGH, and a temperature range of 22–28 °C (72–82 °F). It feeds on worms, benthic crustaceans, and insect larvae. It lays eggs in dense vegetation and adults do not guard the eggs.

Famous quotes containing the words appearance and, appearance and/or anatomy:
“Never before has a generation of parents faced such awesome competition with the mass media for their children’s attention. While parents tout the virtues of premarital virginity, drug-free living, nonviolent resolution of social conflict, or character over physical appearance, their values are daily challenged by television soaps, rock music lyrics, tabloid headlines, and movie scenes extolling the importance of physical appearance and conformity.”
—Marianne E. Neifert (20th century)
“February is a suitable month for dying. Everything around is dead, the trees black and frozen so that the appearance of green shoots two months hence seems preposterous, the ground hard and cold, the snow dirty, the winter hateful, hanging on too long.”
—Anna Quindlen (b. 1952)
“I love to see, when leaves depart,
The clear anatomy arrive,”
—Roy Campbell (1902–1957)
