Thanks Hara, that's what I thought. I have lots of live rock for the brittle star to hide in and so I was thinking it would probably be okay. I'm going to go get one this weekend, hopefully they will still have some. I was doing some reading on the subject and read that some fish might try to eat the brittle star as well but I only have a clown fish and four pajama cardinalfish so I don't suspect them to cause any problems. The only other inhabitants are all the stuff that came on the rock. A worm, a tiny starfish, a slug, some weird flea like creatures that zip around the rocks, oh and some snails I bought.
I was also considering buying another clown fish as a mate for the one I have. Does that sound like a good idea?
I also have some mushrooms that I bought from live aquaria awhile back that are thriving. I want to get some more of them and possibly something else that will do well without alot of lighting. Any suggestions?
I haven't had much luck with feather dusters and I'm not sure why.
