What do electric eel's eat?
Grown eels eat little fish and babies eat insects.
It also shocks a human and leaves a sting, or it shocks its
prey.
Electric eels can eat fish that are good in size for them and
they have been known to shock them. An electric eel has its charge
for defense and to (like lots of eels), kill and eat smaller prey,
like fishes. Electric Eels are predatory fish that will eat almost
any animal that's small enough to fit into their mouth. In the wild
this mainly includes fish, invertebrates and small mammals. You
will probably have to feed them live fish at first but usually they
can be trained to eat dead freshwater fish such as defrosted frozen
smelt.
They can grow as large as 8 feet long and can weigh as much as
45 pounds, although the size attained in an aquarium will be
smaller. They are not a particularly active fish so they will not
need a tank as large as other species their size would require. If
the tank is longer that the fish is and it has plenty of room to
turn around, it should suffice but remember that even in captivity,
this fish can grow to over 4 or 5 feet.
