got a friend who has a silver, no idea how old it is really and ive only seen it a couple of times....the story is my friend is planning to relocate and he plans to leave his fish with me or my brother. the problem is his silver has got one upturned gill plate, not that severe but i estimate it needs to be operated on quickly. i have no previous experience with this and i really dont know how i could put the fish to sleep when operating....what meds to use, etc. once i got this step figured i guess i can take it from there. help guys.....
