Search for some of my old threads about E cats, the normal malapterus electricus (sp?) can get closer the 2.5-3ft but I've never seen pics of one over about 2 feet and never heard of one in captivity over 16". I kept synodontis species catfish with mine for a year or so just fine, I had heard they were immune to the e cat discharge and decided to try it. The theory held. Syno flavitaeniatus and syno multipunctatus were the two species I kept with mine. E cats are probably my favorite catfish species, period. Lots of character, very hearty, slow growers so you can keep them for a long time in relatively small tank sizes. ~Trent
