3 fish is too much for a 10 gallon....what is your setup like? Lighting, Skimming, Live Rock? If you have PC lighting, you could keep some Zoo colonies, a shroom or two, maybe a small LPS frag. IF you have the NO bulb on a standard 10 gallon hood, maybe some low light shrooms or Zoos. For fish and inverts, I'd get a clown, maybe a goby of some type. 1 Cleaner or Peppermint shrimp. I personally wouldn't keep an anenome. It seems like even the experts in here have trouble keeping them. Hope this helps, Mike
