i have been looking to purchase a "group" of this beautiful fish for some time now. The issue is i would be adding to a 90 gallon species tank which currently houses 3 Mbuna species (Yello Lab, Purple Acei, & Marmalade Fullerboni). I guess my broad question is: if you know the WILLIAMSI, what would you do? Should i pull the trigger, what is your suggestion for ratio between male and females. And overall, i'd enjoy some thoughts on this fish in general.
