Today i got a 6" Tiger Oscar for free from an add on my local websites classifieds section. the seller had it in a 33g tank. it has a pretty bad case of HITH and one cloudy eye. iv never had to deal with this problem before so i have some questions. whats the best way to cure this? can it be cured? do i just need to do lots of water changes and feed him a proper diet? will the holes eventually go away? will his eye ever heal? such an eye sore to look at (no pun intended) besides how the fish feels 
Thanks.
Thanks.
