How to treat hole in the head disease in Tiger oscars
'Hole-in-the-head ' or 'Head and lateral line erosion' is a condition that affects many fishes. A protozoan called Hexamita causes this health condition where the fish species develops small pits or depressions on the skin, which leads to the disfigurement of the fish. The severity of this condition varies for each fish species and is not necessarily fatal. Water change and the removal of active carbons in the tank or aquarium water help cure these fish species' disease. Ninety percent of tank or aquarium water needs to be changed to reduce its carbon contents. Another way to cure it may be isolating the affected fish to a new aquarium with no affected fish in the new water.
