lonely jewel

Long story short I got a tank and it had four fish in it. One of them croaked as soon as I got it home and so I had two jewels and a pleco left. The next night there was a heater malfunction and I lost one of the jewels. I won't be setting up my 55gal cichlid tank for at least a couple of months, just have too much on my plate as is right now but I don't want this fish to be lonely. She's in a 10gal now and none of my other tanks have suitable tank mates. The pleco just got moved to my angel tank and she/he is in there all alone now. I can set back up the 20L she came with until the 55gal eventually goes back up but I'm not sure how to make her more comfortable as far as tank mates go. I'd get another jewel but I don't want to end up with a breeding pair. When the 55gal goes up I know I want firemouths, it's supposed to be a SA/CA tank. I don't know, what do you suggest I do?

How big is the jewel?

probably 2 1/2-3"

rainbows, jewels, firemouth, really any small ca/sa fish should be fine... wouldnt go much bigger than firemouth though... maybe jack dempsey, but you'd be pushin it big time. I really like the cockatoo cichlid ( Apistogramma cacatuoides ) they might be a lil too small if you go with firemouth and jack size fish though.

I don't want rainbows again, would company of another species make her feel more comfortable though? I've done some reading but haven't found a great deal of the jewels social behavior and what they need to be happy(as far as tankmates go). I would love to get another jewel but if they become bonded I don't want them claiming a whole 55 to themselves. Anyone have jewels for sale on here?
