Early in January 2013 upon returning from holiday, I found that one of my two Ocellaris Clownfish have gone missing without any trace. The guy that looked after my tank while I was gone, also did not see a dead clown fish floating around. I was quite baffeled and eventually came to the conclusion that he must have died and that the clean-up crew did their job to leave no trace behind. I built two overflow units to get the water from the tank to the sump with a catchment box for each overflow outside behind the tank. For the syphon to work the catchment box must be half full - about two liters of water. The catchment box is made of a slightly transparent plastic and one cannot clearly see through it. Earlier this evening while doing my bi-weekly check of the syphon boxes I saw something moving in the other catchment box. At first I thought that I my eyes were deceiving me. Upon investigation I could make out through the frosted plastic of the catchment box that it was a clown fish swimming around in there. I checked my tank, as I thought that it was the clown fish still left, that tried to escape, but he was there swimming happily in his little "ocean". I just had to call my wife to come and see this because there was the missing clown fish swimming in the catchment box almost 6 months after it has gone missing. It was healthy, but much smaller and paler around the cheeks than it's mate. I immediately turned off the tank's lights an reintroduced him to the main tank again. I was afraid that his mate would attack him, as he is now much smaller, but they teamed up as if nothing has happened and carried on swimming together as in the good ole days. I figured out that he must have been living on the few small pieces of pieces of flaked food that floated into the overflow during feeding times, and a huge amount of luck. How he got there still keeps me guessing. Well..... Miracles do happen and this is proof of it.
