Hi, I think I'v gotten over the ik I had, and I think I'm ready for another fish. I really only want one (and an inexpenceive on if possibe...) in case there is still a parisite in the water. Right now all I have is a yellow tang, a long nosed hawk fish and a white ribbon eel. does anyone have any ideas on a good fish I could get that would get along with what I have and I would be able to see ik spots on it if broke out? Thanks!
