hi
i am using a underwater filter in my 3 gallon tank. and my 2 red and blue colombian tetra keeps "challenging" the jet of water that the filter spits out, and when they are not "challenging the get of water, they seem to be very active in swimming against the water flow...is this normal? wun they tire themselves up, or even stress themselves up and die? or is my filter to strong for the 3 gallon tank?
