Is this ick?

After reading countless threads on this Ich subject I just have to say. I have NEVER had an Ich problem.How do I account for this?Luck?? Can't be that I am the most unlucky person on the planet.;D Never even seen one spot on any fish. (This is not to say it has never been in my system.)I have NEVER used a QT tank.I acclimate by dropping the bag in for 15 min.and let her/him go. I contribute my success to a few simple rules on SW fish.
1-Never overcrowd your tank. SW fish require alot of space compared to FW fish(species dependant).You have to keep any aggresion to a minimum.Aggresion can take on many forms for fish and does not always include biting or chasing.Simple posturing threats (sometimes physical and or vocal)can be stressful over long periods.
2-Selection. Never buy anything be it invert/fish unless you have witnessed it eating.(Of course this is hard to do with online purchases.)
Inspect the specimen carefully.Buying nothing is better then bringing home death. Be selective to increase your odds of success.
Always research what you buy. Don't buy it if you don't know what it is.
3-Water quality.Keep up with your WC or other form of nutrient export.
4-Enviroment. You want to create the right enviroment for the fish/invert you select. Proper aquascaping can help you get the maximum ammount of space out of your tank and keep your fish feeling more at ease.
5-Feed a variety of foods (After all it is the spice of life) but never overfeed.Good nurition builds a healthy immune system.
After all this is said and done my point is a healthy fish in the correct enviroment should have the means to combat this parasite on its own. I have had incredibly good luck at keeping fish and inverts. for long periods of time using the above methods.If Ich could attack and kill healthy fish none would survive the ordeal they go through before they reach your house.

 

A little update,

My puffer is being really skittish and I have not seen it eat since I last posted. I see him around once in a while and i attempt to feed it but will not eat anything. Is he possibly eating something else?
