thank you guys for the advice/help 
i already did 50% WC and put 6 table tablespoonof salt, then aqua care & methyline blue, its about 12hours now but nothing changes.... i removed all the ornaments, only gravel and 1 purple rubber left inside the tank to avoid more damage. im going to store later to find more treatment...
