The fish with the blue face is an aulonocara red (in this case he's more orange than red) I have 3 synos in that tank - one hangs round the front and the other two on either side. The only time I see all 3 together is feeding time. There are also 3 electric yellows, 3 marble aulonocaras, a pair of juli transcriptus and a bristlenose in the tank.
