Just over two weeks ago I purchased a 2" Diamond Goby and a Coral Beauty Angle from my LFS. They were in my QT for two weeks as of yesterday. I noticed the Goby wasn't acting normal on Friday and Saturday was to be the day I introduced them both to the DT anyway. I am using Carib Sea live sand in my QT and was feeding him both Mysis and Brine shrimp which I saw it devour every evening at feeding time. I even bought a reef feeding tube last week so I could place shrimp into the sand for it to sift thru. I think it may have starved to death despite me seeing it eat every day big time. It's stomach never looked plump to me as I have read it should. My hope was that my 1 year old DT would have enough in the sand to feed him but this morning I found my cleaner shrimp on top of it. I also lost a Two Spot a couple weeks before this and am pretty sure it starved in my QT. What is the key to successfully keeping a goby that eats from the sand? I need something in my DT to turn over the sand and sift thru it.
