Bare bottom and Invertabrates.

[Todd]

I know that there are alot of threads about BB tanks, but I did a search and I couldn't easily find what I was looking for.

I am setting up a 75g with 33 gallon sump this week that I just picked up, and am thinking about going BB (hopefully transfer over my livestock before the weekend). I am thinking barebottom mainly because I spent all of my money on the tank and lighting, but also because I think that it will make maintenance easier, and although I like the look of a sandbed I don't like the look of a dirty sandbed. Additionally I have read that it is a bad idea to transfer the sand from an established tank to a new tank, as stirring it up that much releases alot of nasties - is this correct?

My question is this - how are my crabs and snails going to do without a sandbed? Also, by not having a sandbed, what livestock options am I eliminating (e.g. Brittle starfish, golbies, ect)?
