sickness

Question
I have a small school of tetras in my ten gallon tank, and just recently one of them has died. Before he died, he was swimming in a twirling fashion and had trouble staying upright, then eventually he stopped swimming and deceased. If you can, please tell me what was wrong so i can prevent it from happening again. Thank you

Answer
Hello.The trouble staying upright was caused by swim bladder disorder. Swim bladder happens when a fishs' air pocket gets disrupted but in this case it happened because he had an advanced illness. By this stage there is nothing you can do for the fish. Clean your tank and add a small dosage of salt (disolve it first) this will help prevent an illness.
