I'm going to keep the cuke in mind for my tank... I'm having the same problem. I just bought a bullet goby to mix it up a bit. He's a good 5" so he is able to cover a great deal of sand when he gets used to everything. Right now he is shy and only takes a bite at the sand a few times a day.... Or that's all I see anyway. I want to get a queen conch for my tank. It would be neat to see how big I can actually get it in my tank.
I got a zebra brittle star too to eat so e of the deterious... But I havnt really seen it AT ALL since I put him in there. He might be out now since its dark...its like 12AM right now.
Good luck with it though. If you find a good solution, let me know!
