Read an interesting thread by rd, explained the use of epsom salt soaked with pellets in addition to antibiotics. The epsom salts apparently kill the parasites, if you see stringy white feces most likly intestoal parasites causing the hole in the head, would search for this thread for a complete explaination,
For the ducklips it is cureable, I have cured it several times in fh, best results daily 50% water changes, with metro and bifuran added to feed (need to treat infection internally) add the metro+ to the water for the columaris, combined with raised temps. This treatment should cure both the hole in the head and the ducklips.
