Best Bare Bottom Pico CUC?

[SkullV]

Looking for something to eat detritus in my bare bottom Ecopico in between weekly water changes. I already have a few Asternia Stars that came in as hitchhikers, and I know they do a good job.

Stock list is:

• Acans (already have)
• Duncans (already have)
• Hammer (already have)
• Scolys (already have)
• Phoyosynthetic Gorgonian (already have)
• Toadstool (already have)
• Green Star Polyps (already have)
• Pom Pom Xenia (already have)
• Short Tentacle Plate (already have)
• 2 Florda Cerith Snails (already have)
• 1 Astrea Snail (already have)
• A. Ocellaris (adding next week)
• Cleaner Shrimp (adding next week)

Any idea of what to add to the CUC or just leave it alone?
