Sadly my partner came down this morning to find my 8" tinfoil barb dead on the floor. On examaning my tank, an 18" piece of bogwood wieghted with rocks had moved a foot or so, suggesting my 10" oscar has been up to mischief. One of my condensation trays was also up in the air on the edge of the tank, indicating Gills (his pet name)exit point. Very sad, even moreso as he was off to a new home today.
