Thanks for the advice.
I think I will try to get about 10-12 juvie WTH, if Dave's still has them, and then remove the extra males if/when necessary. If I don't get enough females for 2 males, then I will keep one.
I am assuming they like plenty of rock-work like most mbuna? I have some holey rock I was thinking of using. Also have some large mature plants in a smaller tank I thought I would move
to the new one.
