ok cool . im planning an all male tank to with species that dont look too similar , so i get more colour. . did a lot of reading on mbuna last night and i dont fancy them so much now , but after further reading peacocks seem more peacefull and easier to mix by african standards . with the males still being stunningly coloured. also i know that the dominant males colour most with less so ones being a buit more subdued. so i have tried to choose species af all similar size but differently coloured/marked .
