To go into a 75G tank with Malapterurus Electricus, Tilapia Butticoferi and Polupterus Lapradei. The only fish that comes to mind is a common pl*co or a gibbiceps, since they get big and armoured, but I really want to keep this tank as a riverine african habitat. What would you recomend?

BTW there are tons of hiding places and neither one of the fishes is overly aggressive

A Giraffe-nosed cat, Auchenoglanis occidentalis would work out fine for a while eventually you would need a bigger tank. You could also try some riverene Synodontis.

How big is your M. electricus? NO fish will survive for long as a tankmate in a 75 gal of an electric cat > 20 cm or so.

He's 6" and I haven't seen him bother any fish yet, not even much smaller jewels! I'm sure its just a matter of time ofcourse...

and if the Malapterurus won't finish him, the buttikoferi will....that is pound for pound one of THE nastiest fish available for homekeeping!

if you want to hang on to these species, I'd suggest you get an upgrade, like a 150G tank or so.

Actually butti is moving to his own tank in the next couple of weeks. What do you think of keeping Malapterurus with various bichirs (polypterus) species? What abould elephant noses? Or, are there any other fish specifically known for being somewhat electricity resistant?

Plastic ones are the only kind that come to mind. Even with another e-cat, one of them is likely to eventually kill the other. I would think you'd need at least a 1,000 gal tank to keep two e-cats together.

I've seen a 10" electric cat kill a 1,5 foot long Clarias batrachus once........

cats don't come much tougher than C batrachus!

that particular electric zapped me a few times when it was still a wee 5-6" and we just bought it for a few bucks (they wanted to get rid of it). not a nice experience, especially when carrying the fish in a wet fish-bag under my shirt because it was cold outside.......

and the bigger they get the bigger the zap!

What??? Really I did not realize that the electricity could transfer. If you are doing water changes can it zap you through the water?

I've had my 6 incher for close to 2 months now and it is yet to zap ANYTHING! Never zapped me, didn't fight back when super-aggressive tilapia butticoferi attacked it, and its been peacefully coexisting with 3 bite-sized jewel fishes for over a week now
