Sad day, today. I was cleaning my tank and apparently, I cant see because I killed my masked goby. Was wondering why my snails came out from the sand and when I looked around. Crab already chomping away at the goby. I cried. Worst of all had the fish for about 24hrs. Can't find my Rainford goby either. Not sure if I killed and buried it some how or if he's in shock somewhere hiding. I feel pretty bad.
