I wouldn't keep Yellow Labs with Blue Ram though, that's sort of a risky combination. I'd either go with an mbuna tank (using Yellow Labs, with Acei also maybe) or a community tank with some Blue Rams, not the two together. For an Mbuna tank the only fish that could be classified as a cleaner that I've seen work out most of the time are Synodontis Catfish. For the community with Blue Rams you could use any community cleaner. I wouldn't get a fish just to be a cleaner though, maintenence is better than using a fish (and nicer to the fish).
we had a syno occelifer for about 2 years, until he kept wearing out his fins on the rocks, we had to take him back to the lfs and he is really beautiful, we didnt want to take the chance of something like that happening again..so I just look at him everytime we are up at forest lake...and I still call him spot... he was an awesome cleaner....especially of unwanted fry....:huh:
