Hi BreckCo! I would suggest getting a good book or two. I've gotten several from the big auction site fairly cheap, you just have to know which ones you want & keep looking for them often till you find one in your price range. One I really like is called Aquarium Corals by Eric Borneman. There another one called Corals by Julian Sprung that's erally good. You can also do a search on here and probably get some info. I think the hammer & the zoos will be fine next to each other though. What color is your hammer? I have one that i've had for a while now, it has 7 heads on it that have all formed 2 mouths now & looks like they are all dividing, it's metallic green by the way.
