Thanks for all the suggestions guys. I actually found a couple Pseudotropheus socolofi at my LFS and bought them. They are really beautiful. LOVE the black border on the dorsal fin when they flare. When I first introduced them, my acei, which is about a 1/2 inch bigger than they are, tried to push them around. That lasted about 30 seconds before the socolofi turned things around on him, haha! They have not been pro-actively aggressive since that time, but do hold their own. Their aggression level seems to be about perfect with the red zebra and the acei. The labs are a little more mellow, but no one picks on them yet. They have been in the tank the longest and it seems like the rest of the crew respects that.
Neither of the socolofi really have egg spots. One of them has like half a spot on the distal part of his anal fin. Is it likely I have two females? I hope not.
Another question, my LFS also has some electric blue johanni. I've read they are extremely contraspecifically aggressive, but I love their coloration. Would it be ok for me to have just one in the tank?
Thanks guy. I'm cichlid hooked. Setting up my little 10 gallon with a pair of julidochromis ornatus tomorrow.
Thanks!
