Who Gives A Fish Forums

I recently picked up 7 assorted cichlids from my LFS, and 4 of them have this awesome yellowish-orange color going on. The other 3 are blue with stripes that show up every now and then.

I managed to snap a few pics, but it's tough since they freak out and hide whenever I get close to the tank. When I'm far away, though, they're super active.

They're currently in a 55-gallon tank, and I'm thinking of adding more fish to get a total of 15. Before I do that, I wanted to figure out what kind of fish these guys are.

The orange ones appear to be either Red Zebra (Metriaclima estherae) or Kingsizei Lupingu (Metriaclima sp.), though I'm far from a cichlid expert. Both are from the Malawi/Victoria region.

The blue ones seem to resemble Chinuni (Cynotilapia zebroides) or possibly the "Metangula" variant, also known as white top afra. Again, these are Malawi/Victoria rock dwellers.

I'm basing this off of some research from african-cichlid.com, specifically their Lake Malawi page. I'm not familiar with size or specific requirements, so I'll leave that to those more knowledgeable.
