Tank - my tank is not finished cycling yet but I am going to add a pair of clowns when it is ready. I have universally been warned about the damsels being territorial (and hard to catch if you need to pull them out) - so I am going to pass on them.
Have you planned out the other species you want yet? It is a good idea to do that as there is a maximum capacity (even lower if you are planning to have corals). You will also want to review fish compatability (chart on here somewhere) to make sure that everyone is likely to get along.
I can't wait to hear about your progress - since you are ahead of me and can lead the way! Good luck and have fun!
