I had a freak accident last night, Knocked a cup of coffee off the table onto the lid of my 55. The coffee cup hit just right...most drained in crack of lid into the tank.
Should have seen me running around like a fool draining and refilling to dilute. As of this morning all fish are fine (south american tank diamond tetras and dwarf flag cichlids). There was one odd thing..all fish were on my side of aquariunm watching me intently...drinking my first cup of joe.
Anyone else do something along these lines, would love to hear about it, as I dont want to feel alone in this misadventure.
