What are you referring to? The fresh water fish or fresh water tanks in general?
I'm preoccupied with life now and I'm not on the forums as much and I just got respiratory work with a temp agency, a registry, that hospitals call when they're short staffed. I have only worked in a hospital as an intern and I'll be thrown into hospitals I've never been to and it'll be a lot of freaking out before I get a handle of this work.
