These are almost certainly Cammalanus sp. which bury there spiked heads into the intestinal wall. I have managed to completely erradicate them using a drug called Levamisole hydrochloride (levaside TM) which is a livestock wormer. I'll dig out the doseage later and post. I'll just say first that this is a real pest to dwarfs and killies. I introduced it into a 55gallon holding/grow out tank at one time via a pair of A.cacatuoides and almost as soon as I noticed it nearly all the other fish were infected. I tried piperazine (human worming powder) which I soaked bloodworm in and it seemed to lessen for a while but soon came back worse. In the end I lost many fish including most (~15) of my A.nijsseni fry which were just sexing out. If you can't see it yet on your other fish you must remove them now before it is too late. When you use a treatment method though treat all fish that have been in contact with the infected fish. Ken.
