Eels do not discharge electricity. It is the electric eel that discharges electricity. Although there is an eel word in its name, it is actually not a real eel, but more similar to a catfish. The electric eel's body structure is very special, its muscle tissue constitutes the discharge body, the head is negative, the tail is positive, the western part of the body is similar to a laminated battery, when stimulated by nerve signals, it will make ion flow through the cell membrane, thus connecting the discharge body in series, releasing 600-800 volts of high-voltage electricity.
Above, electric eels can release 600-800 volts of high-voltage electricity, enough to electrocute a cow, so electrocution is also very possible. But this is its highest voltage, averaging about 350 volts, and the current is usually less than 1 ampere. Humans are usually knocked unconscious after contact with electric eels, most of the deaths are due to drowning after falling into the water, electrocution is not common.
Electric eels like slightly acidic or neutral water quality, water temperature should be kept above 15 degrees Celsius, as long as there is a slow flow of water, no additional filtration system is needed. Moreover, the fish can breathe air directly without worrying about the problem of insufficient dissolved oxygen in the water body. It is worth mentioning that because it has no teeth, it can not catch prey by biting, mainly by discharging electricity to electrocution, so when feeding, we must be careful not to put our hands into the water.
