Depending on where you go with your tank, you may learn to really hate that CBS. If you start doing corals, mine would literally pull food right out of the corals mouths. Needless to say, mine was banished to a QT tank over a year ago after a few months of being a pest to everything in my tank. With a 75g though, you may not have those problems since he has more room to roam. They can be quite entertaining though.
