Ich or White Spot
Type:
Parasitic
>>caused by Ichthyophthirius multifiliis
>>
the Ichthyophthirius is a ciliated parasite that
affects virtually all fish species
>>
this parasite penetrates below the skin and transforms into a
stage known as 'tophont', which feeds on the fish's body cells
and fluids
>>
the trophont is known to continuously move under the skin
>>
the trophont eventually matures and exits out of the skin,
clinging to an object (such as a plant) as an encapsulated
organism known as a 'tomont'
>>
the tomont repeatedly divides to produce hundred of 'tomites'
which eventually hatch and swim to find a host
Symptoms:
>> presence of small white spots (which are actually
cysts that contain active trophonts) all over the body and fins
>> rubbing of body against rocks and pond surfaces
in early stages, lethargy in later stages
>>
can lead to severe hyperplasia (abnormal cell growth), tissue
damage and bacterial infection
Remedies:
>> easily treated with commercial ich medications
if carried out over an adequate amount of time, since only the
free-swimming stage of the parasite can be dealt with
>>
long-term or indefinite salting of the pond (0.2%) will also
help address the problem
