I used to have an oscar that died several years ago. Even if he died, I am curious why he died. Behaviors before he died were refusal to eat and staying in the same location of the tank.

Without being able to carry out a post-mortem is nearly impossible to say for sure. However, if I was forced to guess what could be wrong, then I would probably face some kind of parasitic infection, maybe hexamita. The stomach looks like it sunken slightly, and fish often become motionless when they have this sort of infection.

I may not always be right, but I am always the BOSS :-)

Have oscars died because of a parasite?

yes, parasite such as hexamita can cause death... slow death as such...
normally hexa is in the fish digestive system but will never manifest when
immune system is at its best... however, in any moment the immune system
is down, it will attacked the fish and develop fast... white stringy pooh, not
eating coz the fish feel always full...

but your picture shows some fragments with the fins... which make me
to believe there is also some water quality issue triggering the stress for
the fish...

The photo was after a water change if I am right. There is one problem though during that time. I think I remember I cleaned 100%.

fish sulking immediately after cleaning and died few day later

Just wondering is cleaning filter good or bad? If so how many times a month?

You have to clean the mechanical contents of any filter. Sponges, pads etc. Reduced filter flow is an indicator that time is up. Never clean or disturb the bio portion. Remove the bio, set on tank bottom or in a separate pail of tank water. Rinse or replace the mechanical, again using tank water. Also good to clean the filter impeller and magnet from time to time. Frequency will depend on overall efficiency of your filtration, tank stock and bioload.


I may not be the Boss, but I'm ALWAYS right!
