i know SOME stuff about e-eels.They do make great pets once they get settled in.Be cautious as they have a shock that can stun a horse(800 volts,i think).There sort of expensive like the most ive seen is 126$.Also,when cleaning the tank,NEVER use a metal net.Use a wooden one.Never touch it(I think we all know that).They need a relatively large tank.not huge, they can grow 3 to 5 feet in home aquaria.They are voracious little beasts,and will probably take anything(well,sort of).Squid,fish,shrimp,and silver sides are good foods for them.A heater is also requiered.
