Cleanup Crew for 5 1/2

[shawnkenn]

Can someone give me any ideas on a cleanup crew for my 5.5?

My tank has been running for 2 weeks now all my test results are in range but nitrates are at 20. I'am running 2 13 watt bookworms(waiting for my 50/50 from hellolights) I would like to keep every thing small if I can. Thanks for the help. Shawn

I had a 5.5 for many months (its now a refugium) and all I needed were 2 astrial snails and 4 blue legged hermit crabs. There is now a 3 inch bristle worm contributing to the effort.
