I am getting a 150 gallon tank hopefully this weekend. 6 feet long 23 inches deep and 18 inches tall. I currently have 4 mbuna cichlids and an african featherfin catfish in a 29 gallon tank and I was thinking of moving them to the new tank eventually. What other fish could I get? I would like to get something big and different but I dont want to spend a bajillion dollars on a fish. I like colors or oodness. I am pretty new to fish keeping so I dont know much. Help me?
