Like Katie said, they are salvini cichlids (Central American).
As for the 55 gal...it is set up and running...barely.
I'm going to give it a good week or so before adding the salvini.
Forum should be back up and running back the way it used to by then, so I'll start a more permanent thread on the setup later.
Right now the tank is a rough 'throwing together' of a bunch of random driftwood, rocks, fake plants, and cave ornaments I had laying around. It's embarrassing to look at right now, so I'll post pics once I've gotten the $$$ funds to get it a little closer to how I want it to be set up.
Thanks for the comments.
