my oscar has been sick for two days, not eating and just kinda laying around the botoom of the tank and hes just starting loosing scales on his head, he is 10 years old, so im not sure if hes going or has a disease, my other oscar is fine but not eating normal either i think its worried about the other one?? what do you think??

is it just scales off the head or can you see little holes? Also how is the water chemistry (Ph ammonia nitrite nitrate)? What is the tank size? BTW ten years is a long time to have an oscar good job

i dont have the stuff to check the water chemestry, but yes its just scales and the tank is a 60 gal, and i only have the two, hes also taking big gasps of are in, like blowing smoke rings constant.I chang the tank regularly and do every thing the same all the time. he may be older then ten our friend had him before me, so maybe 12 at the most...

i would def get a water testing kit. Those results could point us in the right direction. Are both os acting strange or just the one? Do they get into fights alot? Sometimes my os will get into a fighting mood for a day or 2 and not really wanna eat. In a few days if water chem is good he should come around. Lost scales sounds like fighting or hitting a tank ornament

sorry i can not be of any help but 10 years wow thats a good job
and has the O had HITH befor any other sickness yu can
remmeber

yea it has happened where they have not eaten befor, but no they really dont fight,and just the one is acting strange, the scales are comming off all over the back of the head and hes also really bloated and where it poops or pee's, its really swollen? Hes never been sick before?? but wouldnt he just die if it was old age?

If i read things right you have 2 oscars in a 60g. Well 60g is not really big enough for 2 oscar, 75g is the minimum. You do need to get a test kit for Ph, ammonia, nitrite and nitrate. In the meantime do a 25% water change every 2 days. Only feed what they will eat in 2 mins
