Forms nest in dense plant-growth; has 
been bred in aquarium. Demands live 
food, preferably crutaceans (Daphnia, 
Cyclops, etc.). Dr. Hugh M. Smith ob- 
serves: “Judging by its behavior in cap- 
tivity, this dainty little fish eats only liv- 
ing, moving food. Even when hungry 
it refused chopped meat. When supplied 
with white-fish fry and trout fry it ate 
them promptly, but without great avid- 
ity. One fish which struck at a trout fry 
failed to grasp it, and, although the fry 
dropped to the bottom dead, the sunfish 
did not notice it further. Another stop- 
ped following a trout fry to pursue a 
gammarid. Insect larvae and small 
crustacea were always eaten readily, and 
such animals are doubtless the usual nat- 
ural food.” Mesogonistius, middle-angled 
sail, in reference to the contour of the 
dorsal fin; chaetodon, bristle-teeth, inap- 
propriate in direct application, and given 
because this sunfish resembles in colora- 
tion some species of the salt-water genus 
Chaetodon. )
