Has anybody had oscars with fin rot? Im trying to work out if my oscars have fin rot or just been nipped at. I'm just after some basic facts even pictures in regards to this disease.

first question is: do you have fin nipper tank mate?
are you sure it is rotten fin???? in some occasion,
the new lining at the end of the fin misconstrued to
be rotten fin....

i don't have any experience rotten fin with oscar

I did catch the electric yellow nipping at the tail on my tiger oscar. The end of his tail is a little corrugated, not the normal curve of an oscar tail. There are bits missing from his tail, his front underside fin and a little from his dorsal. If it is fin rot I just want to catch it. If I have a nipper, well may have to move him.

i understand that fin rot is a fungi infection and before
it could affect an oscar, it will develop fungus in the
body or HITH first before the fins..... however, there is
a theory that fin nipper usually attacked sick fish or fish
that has weak body.

so fin rot is more a secondary infection. so it is more likely it will have to have something else first. thanks for that. I think i may be pointing the finger more the the yellow but will keep a close eye on him.

treat with melafix to stop secondary infection or fungus setting in the nipped fin ends.

can i just put the melafix straight in the tank? or will I have to move them to a separate tank? does the carbon need to be removed?

yep you got it ........remove the carbon and treat them where they are....this should be ok but remove any invertabrates.before treating

great. thanks for that:)
