Answer 2

Hole-In-The-Head Disease

Cause and Symptoms

The cause of this condition is Hexamita Protozoa , parasitic organisms that are highly contagious.

These parasites thrive with poor water quality management.

If your fish has this condition, you will notice the appearance of small pits and pimples mainly on the fish's head. These pits will simply grow and form bigger pits.

The pits are white in color, and sometimes mucous are visible around them.

In addition to losing weight, becoming lethargic, and losing their appetites, the fish will produce white, stringy f***s.

Treatment

Add Dimetrydazole (5mg/l) or Metronidazole (7mg/l).

Repeat treatment once every 3 days.

Do a 20%-30% water change.

It is sometimes necessary to inject Metronidazole, but injections near the affected area should be attempt only by qualified personnel.

Preventive measures :

Change your water regularly.

Quarantine new fish for three to four weeks.

Avoid cross-tank contamination.
