What the heck is a hybred oscar? As far as I know there is no such thing as an oscar hybrid other then the possability that they may be hybridized with other Astronotus species but I fail to see how this would be a problem.
As for HITH, you need to answer p45's questions. HITH is caused by poor water conditions and a bad diet. Even if you heal this oscar they are prone to get it again if the proper measurements are not taken.
