I just bought a new 55 gallon tank, it'll be at least a couple of months before I get it set up. I am just trying to decide what to stock when the time comes. I posted in the general african and got a few tips, I did check out the cookie cutter stocking section. So far I really like the Cynotilapia Afra. I also like the Pseudotrophius Sp.(Msuli). How many should I get of each? I do want variety and color. What would be a 3rd or possibly 4th species I could have with these 2? I am looking into canister filters as that was suggested in another post. Thanks.
