they are in my qt tank but they don't look to good Help

I'm assuming the water parameters are those of your QT.The nitrite reading is far to high I would do an immediate 50% water change to try and reduce the nitrite levels as they are probably the cause of your fish feeling unwell.

no the water parameters are in my 45 gallon. And the two fish are in the qt.

ok i will do a big water change to the 45 gallon

does any one else know why the tail fin is damaged. Help!!!

If you truly have nitrItes of 10ppm, I am suprised that the fish are even alive......

Please do a much much larger water change. With a reading of 10, it is not really worth keeping any of the water - you could only keep 1 quart of every 10 gallons - that is only 1 gallon or a bit more of your 45 gallon tank - to get the nitrite down to 0.25 where it should be at most.

High ammonia, and nitrites cause stress. Stress can cause tails to get red streaks. High nitrites affect the gill function and the blood circulation in the fish. This easily could be the main if not only reason for the "pink"
tails.
