Tankmates for Electric Cat

I just picked up this cooler-than-cool addition today:

http://www.scotcat.com/factsheets/malapterurus_electricus.htm

Currently it's the size of about 1/3 of a hotdog - maybe 3" long and 3/4" in diameter at its thickest part. I know it's a predatory cat, obviously, and gets large, but for the most part, I'm not concerned with that. There are some tetras in the tank, but honestly they're pretty old anyway and starting to die of natural causes, so if they get picked off by the cat, I won't be too bummed. I just hope I get to see it.

My main concern is my 2 adult angelfish also in the tank. I know the cat is too small now to eat them, but will it still try? I have read the catfish generally only reaches sizes of max 12" in home aquaria. I can move the angels if it's in their best interest, but my preference would be to have SOMETHING in with this catfish.

Tank is a 40 breeder, FYI.

Yeah, I will be getting a bigger thank in the next 3 months or so, so size won't be an issue then. The 40B will hold it fine for a while. I'm hoping in that time I can get it trained to eat frozen/live foods that are NOT fish so the angels will be safe.

Yeah, hi, thanks. Yes, I did read it. But I have also read conflicting information - some accounts have them good with larger fish, some say they're strictly solitary.

And did YOU read what *I* just said? Bigger tank. 3 months. People keep ones the size I have in 10 gallons for starters.

I was involved in study of electric eels in school. Hence, my interest in this fish. Since I'm typing to you, none of the eels ever killed me. I think we're good.

Oh, yeah, definitely. We had one eel that was overly excitable, and he jolted me a few times. Felt my heart throw a PVC once when it happened. Not cool. All plastic implements, rubber soled shoes for this kid.

The angels are full grown - bodies the size of the palm of an average adult's hand. I talked to the guy at the LFS for a long time before getting the E cat, and he says he's kept one with a pair of severums no problem, and another with he had to toss in his koi pond for a while (long story) and nothing ever happened.
