hi,ive had my oscars for 3 years now without too many health problems,both fish developed cloudy eyes and now have a cottonwool appearance fungi on eyes.1 fish has an ulcer type fungi which is eroding the base of 1 fin,can anyone help please?

hi there,a photograph would be very helpful, pretty difficult to advise without seeing what we are dealing with.

now what we always ask for, what are your water conditions?

Carry out some extra tank maintenance and make sure the water is in very good condition. If it looks like cotton wool then it's probably some kind of fungal infection. A fungal remedy might help sort that out. Problem is, fungus often forms on wounds. It could well be that William has got infected but it really is very difficult to say.

i concur with the Boss! difficult to give advise without visual
aid. but one is for sure, blurred eyes and crater wounds is a
sign of bad water condition. there must be something you did
recently which you usually do not.

pristine water and varied foods is the first defense against any
fish illnesses.

soz,aint got p.c.knowhow to download photos,but took pics on mob phone and went to vet who says the underlying conditions suggest some type of worm,put octozin in tank y'day and slight improvement but have gone off food now,did water change b4 treatment commenced,but dont know water readings as 4got testing kit from supplier,thanks 4 advise and keep u informed of progress (hopefully).

please see submitted reply,soz ive just seen the quick reply part

sounds like all the above .....but personaly i would go for ph out of range for oscar

what is range of ph level?

octozin will make your fish/es refuse food for a while.
that is why we use to suggest keeping the water in tip
top condition prior to medication so that fish/es had to
take food first. there are times that untimely medication
make the fish/es suffer more before healing.

if i may ask, how big is your oscar? i have a two years old
oscar measuring 14 inches more or less and a 4 months old oscar
measuring 8 inches+/-.

thanks for response,seem to be improving now,eating fish,but not eating pellets yet.going to do 30% water change sunday(is that reccomended?).1 oscar is 13in and other is 11.5 in

hi,did what vet and urselves reccommended and both oscars improving now.well eating fish but not pellets yet,fungus hasnt seemed to improve but both acting normal agaon,does it take long for fungus to go?

with pristine water and varied foods, that fungi will be gone
in a few days from now (3 to 4 days).

have you applied some pure salt? i haven't had any fungi with
my oscar but i did help a friend treating his fish and we did
it the other way. i used hospital tank, import some water and
filter pump from the existing tank, diluted with fresh water,
add methylene blue, raise the temp to 29 deg C, add pure salt
at 1tbs/10gal, operate an air pump to augment oxygen dissolve,
and leave it there overnight. the following day, put the oscar
back to his normal tank and in 3 days, the fungi had cleared.
