Snakeheads protect their young. Most lay eggs and defend them while a few species
are male mouthbrooder. For giant snakehead [Channa micropeltes] even one foot
long young are sometimes still protected. Also for giant snakehead there are
reports since old days about humans getting bitten by the guarding parents and the
result is not too nice ^_^.

Elopichthys bambusa is probably more or less like the Colorado pikeminnow but it
is capable of reproducing in the dam, which make the fisheries people in China
hating them for, though they taste good, they can multiply and decimate any fry
those fisheries people try to stock for their "giant pond" whose rivers were
turned into.
