Hi, I have a 55 gallon tank stocked with 8 neons, cories, 1 angel and 3 rainbows. Recently I got 6 Buenos Aires Tetras. They have by far been my most active fish. Two of my turqouise rainbows have a very small tear on there rear fin. One of them has turned a very very dark blue. What does this mean and could the tetras be nipping?
