Ugh, are you going to not trust me again?????? Photos/lighting changes things. There are only really two albino/white mbuna, and yours isn't an albino yellow lab.
If you think I don't know my stuff.... well lets see I have over 1500 gallons worth of africans have been IDing them for years now... Have been to I don't know how many talks on Africans. Read good lord how many articles. (Heck I was the guy who was in charge of baging and correctly labeling all the donated fish for the ACA in Atlanta...)
Sorry but if this is the tanks I get for correctly IDing fish for you I am just going to let other people have the fun of helping you out.
