first pic...Haplichromis Venustus (Haplichrome)and Labidochromis Caeruleus, Yellow Lab (Mbuna).
It is said Habs and Mbuna should not be kept together but I have them in my tank and have had no problems so far.
How big is your tank? The hap can grow fully up to about 10 inches and the Yellow Lab to around 4 - 5 inches.
second pic...can't make any colouration out, sorry.
What other tank-mates do these fish have?
