Ecology and Behavior
Crazy fish are predatory fish, preying on crustaceans, small fishes, and worms. They are territorial and are most active at twilight and at night.
They are known for their behavior of aligning their body against the nearest surface, appearing horizontal, vertical and even upside down. They use this positioning to ambush prey. They also have the ability to change colors to a limited extent to blend in with their environment. During the monsoon seasons, the reddish margins of the fins can turn paler (to either orange or white), accompanied by the appearance of numerous reddish spots on the lower half of the body. The upper half of the caudal fin also turns white.
