With Camallanus, the worms often protrude visibly from the fish's anus. It is very likely that the infection was caused by live food. Here, it should be noted that the Camallanus genus is livebearing and can infect multiple generations of fish without changing hosts. Camallanus belong to the threadworms (nematodes). ''
