What was the cause of small Yasha gobys death?

[nathan212178]

Sadly my yasha goby died this morning and I am very curious to why it happened, it was eating enough to where I though his stomach was full but I could never tell because of how small it is, all I can say is that it was not starved, he was never aggressive when eating so I had to put it in front of him in order for him to eat, he never moved from the same area of the tank but I thought he was normal at the time. When I picked up his body there was a lot of sand stuck to his anal area. The last thing I can mention is a strange anemone I had picked up and threw away, it was clear and had white tips.
I just want to know what was the cause so I can prevent it from happening again
