so i noticed my istlanum male was looking ill so i moved him to a hospital tank and now i come home 36 hours later and now there are worms everywhere. they are about the size of a pin and white or tan and wiggle in the water column. he looks a little better and i am asuming the worms are from him as the tank was clean before he entered it. what is his problem and how do i fix it any help is great i have never encountered this before. could any of the other fish in the reg tank be affected
