2 days ago i bought the glass top for my tank so i could add a second light fixture...the thing is...when i put it on it was fine then as soon as i put the light on top of the glass the whole *&^%@#$%^ thing fell into the tank apparently the sharp brain who cut the glass had a faulty tape measure because they cut it too short...tank and glass top are from the same company... 8O believe it or not...so i quickly unplugged everything and cleaned up the mess of water and started counting all the fish...they were all fine except i coulndt find one of the 2 otos...since then ive been looking carefully and no signs of him...i changed the water a couple of hours ago and moved the plants around but had no luck...hes nowhere to be found...i even put the whole filter apart to see if he could have been stuck in there...nothing...other than this incindent...my tank has been running smoothly and have 0 ammonia, 0 nitrites and 5-10ppm nitrates...so i dont see a reason why he could have died...is it possible that he died and the other fish ate him??? the list of fish i have are in my signature...im sooo upset with the fish store....why would you sell a top that doesnt fit properly????
