Hi, inside my house i have a "pond" i built that houses some goldfish, lots of guppies, and some catfish. A few days ago i noticed one of my catfish was swimming strange, like something was wrong with his swim bladder. At the moment i couldnt look into it and when i came back he was dead. A few days later i saw the other one and it seemed to have ich. I did my best to catch it but couldnt. It died the next day. So yesterday i started catching and seperating all the fish. Goldfish and remaining catfish in one tank, guppy fry in another, guppies in the last. The guppies are covered in ich and i am begaining treatment. No death yet. But my goldfish show no signs of it. Yet this morning i awoke to one dead. This isnt normal right? If it died from ich there should have been signs?
