The reality of reefing is that we are housing many many lifeforms that can cause some uglies in our tanks. Although some of us choose inverts for their appearance or personality, I would go out on a limb to say that our decisions on inverts are weighed heavily on whether they can handle whatever undesired "inhabitant" is growing on the reef. Do you have a certain invert that is absolutely carrying the team when it comes to keeping your tank looking fresh?
What inverts are doing the best job at keeping your reef clean?
