photo cant c cleary... mean ok la... seldom causes to die...skareb;1302044; said:take pic, if you're seeing very fine holes this could be sensory, your fish is growing to be adult and form those sensory holes, very precise holes. If you are getting HITH Hole In The Head diseases, its more like you get white patches on the head.
There is no know cure for this except to change water regularly, Many ppl suspect Active carbon too long in the water causes it.
Some say too high NO3 - Nitrate is the cause.
FYI HITH very seldom causes your fish to die.
