So I have always loved starfish and currently only have one in my 90 gallon tank. I would like to get quite a bit more but was wondering if there's such a thing as having to many. I honestly would like about 10 in my tank. The wife loves the one we have and wants more as well. What do you guys think?

What are some reef safe starfish that you guys have or have had?

Also do I have to count these as part of my bio load?
