Considering a strictly invert tank

[axepilot]

I have a spare 20G tank and I'm thinking about setting it up as a straight invert tank - some live rock, crabs, shrimp, maybe some feather dusters, etc. What's a good setup for that? I want to keep the filtration simple if possible.

Oops..................looks like I posted in the wrong forum................

Basically, what I recomend for the majority of reef setups: Liverock, a deep sand bed and a protien skimmer (not sure it will do much good due to the usually low-nearly non-existant bio-load given off by inverts, so it's optional here) and a 20 x turnover rate per hour via powerheads. Are you planning on coral? If so, you will need lighting for them, how much exactly depends on what kind of inverts.

I think the thread should be fine here.

I'm not planning on live coral. I'd like to have a feather duster or two, but I'm thinking that they require some active circulation, correct?

Will a simple hanging filter work?

Sorry for the dumb questions, but I've never dealt with a small tank like this or straight inverts.
