Now just this morning I realized how sick my fish are when just yesterday they were fine. I had noticed a little red but not as bad as today... One out of my 6 goldfish died already, the one I had for 4 yrs, 3 almost dead barely even moving. Some fish's tails are bloody red while others are almost all red. What can I do to save my fishes I am extremely sad and going crazy... Help... :(
