MIA: Where did it go?

I came home from work today at around 5:00 pm and noticed that the smallest of my acan frags was missing. It was only a one polyp frag, but I cannot find it in my tank! I began digging around to try to find it, looked in the holes that the diamond goby hides in and still cannot find it.

Other than the diamond goby, the only other thing that I could think of that has the power to take it/lives on the substrate is a yellow brittle star, but do they steal frags?

Will the frag show up again or should I just consider it $15 I'll never see again? I also have a small two polyp frag that was on the sand bed, but I moved it to a lower section of the rock. Should I super glue it down?

 

Oh and I know it was in the sand bed this morning at 5:30 am because I looked in the tank before I left for work and saw it where it usually is.

 

The goby probably buried it! Did you sift through the sand really well?

 

Not extremely well. Would he bury it in the vicinity of his tank, or just in a random spot? I did tear apart his little den looking for it! This is not the first time stuff has gone missing and I have found him later with it.

 

Start gluing the frags given the history you are building with the goby. The way they move sand they definitely can cover coral. If it is small enough it may treat the rock the frag is on as home building material.

 

So just buy a flat piece of LR that is to big for the goby to take and then place that rock on/under the sand bed?
