It depends on what is wrong. Observe your fish closely. Note it's color, any unusual bumps or spots, erratic swimming, appetite, etc. Then take these detailed observations to your local tropical fish retailer. He or she is probably an expert on whatever your fish's problem is. They'll be able to give the best advice on how to treat the problem - if it can be treated.
yes you can rub a sick fish
no, wild fish must get sick if they eat fish food
Fish stick?
I don't really know but what you can do is ask your teacher they can get you sick if the fish itself is sick
No,the fish will just eat your dead skin cells. (sometimes if it is a sick pukka fish maybe you can get sick) it will make ur feet soft tho
no they don't they'll get sick that's why they eat fish the first fish to eat it was a sword fish then he got sick
yes if a fish has the disease and you eat the fish the disease doesn't go away you can be sick but not always Save
Many fish will start to eat another fish if that fish is sick. If your fish's partner is sick, he will eat her until she is dead. I know it's weird, and the only reason I can think of as why they would do that is because they dont want the other one to suffer as much? My fish ate my other fish cuz it was sick.

sick fish loose their color they swim less they hide they stay at the corner they stay at the top or bottom of the tank
There is no reason for raw fish to make you sick if it is fresh and the fish was healthy. The fresher the fish, the better the taste, cooked or raw. When the fish is super-fresh, I like it raw best!
