Yeah I have been holding off on getting an oscar too. I had two, both got HITH. A friend had one and it got HITH too, all store-bought oscars. Now my tank is too loaded to handle an oscar. Maybe someday...
I have heard its most common with store bought or over bred oscars. The theory is that the inbreeding or whatever happens after generations are bred in captivity they may become weaker in their immune system and more prone to HITH. Not sure why this isn't more rampant in other breeds that are bred in captivity so readily. I haven't owned one myself but I had heard that wild caught oscars are less susceptible to HITH. Anyone heard or read anything abou that?
hole in the head is common in oscars. its why i dont keep them.
Mike,
The "markings" , if what I am referring to are what you are referring to, are sensory pits.
HITH looks more like someone took the eraser end of a pencil and pushed it into the O's forehead. The marks which look like a bunch of little pin pricks are sensory pits. The two up front near the mouth are obviously nostrils. Hope this helps!
To add on what everyone else said, O's are messy fish. Require water changes and a balanced diet.![]()
