I've translated quite a few books about aquariums, so I know all about fish diseases and treatments :)

stip = Ichthyophthirius multifiliis (better known as Witte Stip)


ICH (White Spot)

While there are several diseases that the aquarium hobbyist has to deal with, Ich or White Spot is among the most common. In this article we will discuss Ich, how, why, the life, and treatments of it. Hopefully after you are finished you will have a better understanding of this disease and feel more comfortable in its treatment. First off we are going to look at the scientific side of the disease so that we better understand what it is doing.

ICH

Ich, who’s scientific name is Ichthyophthirius multifiliis and it is a protozoan parasite. As in anything a parasite is a creature that feeds off a host to complete its life cycle. The Ich attaches itself to the fish as a tick would do a dog. After attaching it continues to feed until it is complete.

The life cycle of the Ich is a complex one, as by the time you see it on your fish it is already in the adult stages of its life. The general consensus is that Ich has a lifespan of about 10 to 14 days, while there are those in the science world that will go as far to say the lifespan will be as long as 20 days. When you first see Ich it will appear as grains of salt on your fish. By the time that you see it as stated before it’s in its final stages and ready to reproduce. After falling off of the host, it becomes free swimming and will fall to the bottom of the tank or attach itself to rocks and decoration in the tank.

Once the cyst settles in begins to multiply by dividing itself up to as many as 2,000 times. The result of this division produces what is called Tomites. The time frame for this division can vary. In a tank that is 77 degrees F, the tomites will only require about 12 hours to complete this stage as where in a tank of 50 degrees F it may require months to complete.

After the formation of the tomites is complete, they emerge from the cyst as free swimming Theronts. At this stage of their life they are looking for new hosts to feed on. After finding their new host, they will penetrate the fish’s skin and then become Trophozites where the cycle of life begins again. If a Theronts is unable to find a new host within 24 they will usually die.

So now that we have a general idea of what Ich is dong in our tanks lets take a look at what we can do to stop it.
