So, I have a reef tank that has been up for about 6 months with a copperbanded butterfly, three two spot gobies, a juvenile percula clownfish, a condy anemone, a 2.5 in cleaner shrimp, a 3 inch fire shrimp. four hermit crabs, and a couple of green chromis. Problem is that lately a couple of fish have gone missing. About two weeks ago I added two tiny cleaner shrimp, about .75 inches in length. During the day, they were fine, swimming everywhere etc. However, the next morning they were gone!
Then two days later, one of my two spot gobies disappeared too! He was also about .75 inches in size. He had been living in my tank for about a week and a half and shared a burrow with another (much larger and more senior) two spot goby. During the day, he and the larger two spot worked together to build a new burrow. They night I came downstairs for a snack and saw the two of them cuddled up inside the burrow together. In the morning there was no sign of the little goby!
So, I've been very upset about the loss of the tiny two spot and the two tiny shrimp. They have been my only new additions fish wise for the last month or so. I've never had such large and sudden losses before.
I'm wondering if another fish or shrimp or invert in the tank might have eaten them. All three of the victims were pretty small. Also, all three were purchases from Fishtown (I don't usually purchase fish from there). I stopped buying from Fishtown after I bought two clownfish from them very early on and they not only died but I suspected they infected my tank with brooklynella (not confirmed).
So, if it is a murderer inside the tank, I suspect the copperbanded butterfly as he has the largest mouth, the fireshrimp because he only comes out at night, the cleaner shrimp because he looks like he was very full for a day post murder, the clownfish because he's a pig and the anemone because I skipped a feeding a week prior.
Can anyone help shed light on this situation?
