Many fish are labored in their breathing and seem to be surfacing often. 
			
				| 
				 | Fish surfacing and 
				gasping for air is a problem that dictates immediate attention.  
				In aquariums this can indicate: a lack of oxygen, a massive 
				sudden drop or increase of PH, ammonia spikes, over-heating of 
				the water, a toxic contamination of the water or surface tension 
				change.  You'd be surprised at how much damage a little 
				baby oil contamination can do to the inhabitants of your tank. 
				 |  Ponds can suffer from oxygen 
		depletion at different times of the year.  Rotting excess detritus, 
		temperature changes, toxic contamination, water super-cooling during the 
		winter, large amounts of rainfall, pesticides, fertilizers, the list 
		goes on and on.  Without actually investigating the situation it's 
		difficult to diagnose.  Check your pumps and filtration 
		equipment to make sure they're running properly and perform a water 
		change ASAP!  If the fish don't respond to a water change you need 
		to look for possible contaminates and as always, check the PH and 
		ammonia.
