I added sand this past week and will allow it to generate life over the next couple months if need be. I'm also willing to target feed. I would prefer a sand sifter goby to ensure the sandbed remains clean.

Do clown gobies sand sift? I don't recall.

If not then what should I look for?

I keep two. No they sit in coral heads near the top of the tank. They aggressively eat mysis when feed.
They are a very endearing fish to keep. They are so interesting to watch and are very active.

Because the fish is very small they suffer from shipment and are often emaciated in the lfs so see them eat there and feed it often immediately when you place it in your tank so it builds itself up.
Let your sand bed mature with all sorts of critters and than add a bottom dwelling goby.

Thanks guys but I'm really looking for a sand sifting fish, goby or jawfish to keep my sand bed clean. Any other suggestions.

what about an orange spotted goby, or is 24 gallons to small?
