I'm sort of new to this hobby, other than keeping some guppies when I was a kid, and just now got a place big enough for an aquarium, and I have my eye on a 75 gallon tank, for reefs. I've measured already, and I have space to eventually get 2 of these tanks. I might eventually make the other one a predator tank, but for now, I was wondering what would be some good starter fish for a reef tank? I do know I would like to have an eel species, other than that, I'm pretty open.
