Bad news, it can spread to your other fish
Good news, once it's cleared up, their fins will grow back.

thanx for you help. really appriciated. my tank size is 30 gallon. i have gold fish, tiger sharks and angel fish in it. my tank water quality is good. and after seeing that fin rot i am doing frequent water change on daily basis. i think my lovely angel got that problem from pet shop only. rite now i am feeding them freezed worms cubes, pellet food and brine shrimp.

angels r territorial and they may become aggressive to each other if they r crowded and during feeding time.

*To properly calculate the correct number of fish, research how big your fish will grow. *Add all the lengths of all fish as they will be as adults, and you should allow 1 inch per gallon of tank. * You didn't say how many sharks you have or how many gold fish, but the angles alone are enough for a 30 gallon tank. * So you need to get a larger tank, or another one of some size to house the other fish.

#2: *The second problem is that the sharks and angles have different water temperature requirements than the goldfish. * Goldfish are cool water fish. * They do best around 40-70 degrees F. * Angles on the other hand should be kept at 74-84F * *The fins will be less of a problem with the warmer end of their temperature range.
Hope this helps.
