I have recently set up a tank in my office again and have been loving have it around.
I started with a 10 gallon reef, with a 96 quad on top of it. After about 6 months I came across an interestingly sized 30ish gallon tank that I moved everything in to.
The tank itself is doing great the corals are growing, and fish were getting fat.
I had a black and white perc (Great Barrier Reef variety) in it. I had owned him for a bit a year. He was the only fish in the tank.
I came in to work a few weeks ago and to my astonishment he was gone.
I quickly searched the area around my tank to see if he had jumped. No signs of him any where on the floor. I then moved stuff around in the tank looking for his body, or bones or anything that would identify him. I didn't find anything. Chucky(the fish) had vanished.
Distraught I waited a few days and went and got a new fish, I bought a potters angel fish. Named him Harry and put him in the tank. Four days later he vanishes much the same way as Chucky had.
I added one more fish and he too vanished. But this time I had an idea of what was going on. I had the security staff pull the camera footage of thee office and say what appears to be someone leaving the building with a bag full of water. Not conclusive enough to make charges against, but good enough for me.
If I am right the cleaning staff has been stealing my fish.
I have only ever had one fish in the tank at time, and the fish has always vanished the night that the cleaners are in the office. My office is locked when I am not in it, and the only people that have keys outside of the management team are the cleaners.
I have added a couple of more fish and set up a spy cam. I hope to actually catch the thiefs dipping there muddy paws in to my tank.
We shall see.
