I too would warn against a nem. I had a condy one and he ended up taking up the entire left side of my tank. I also endlessly worried about him eating my fish. In my opinion, probably best to leave to the oceans unless you have a really large tank or get a tiny one.

I have a mix of many different saltwater fish amongst my tanks, but I love my Tangs most of all.
