1~What type of fish is afflicted? In addition, please describe what is wrong with the fish to the best of your ability (i.e. cotton like growth, bloated, etc.). Well...I've lost an emperor tetra, a threadfin rainbow, a pristella tetra, and a madagascar rainbow. The Emperor tetra looked like it had tail rot(which I was treating with melafix). The Threadfin rainbow showed no signs of illness. The Pristella began swimming in a near vertical position most of the time. The Madagascar rainbow(as well as my 3 others) swam near the top of the surface and showed no interest in food.
