Picked up a new Mbuna over the weekend and the LFS had him labeled as a "Blue Zebra Cobalt". Cobalts are usually solid powder blue with no bars. To me he looks a little more like a Hara.
Anyways he looked sharp in the tank and was @ a steal price so I swiped him!
I agree its not a "cobalt" zebra, M callainos. Either its the tradition zebra, M. zebra or an C. afra, It does look like C. afra "white top hara" to me. If it stays torpedo shaped its an afra, it it gets deep-bodied as it ages, its a zebra.
