My 55 gallon is way low in terms of number of fish now. It was full of Malawis once upon a time and now it only has three baby Malawis and one adult. I want the take to have cichlids. I am considering selling the fish in there for little money to the lfs or I may restock it with Malawis. What do you recommend? More Malawis or other cichlids? What kind?
