Ich is not what people make it out to be. It can be easily managed with proper nutrition. Think of it like a common cold. Its not that theyre eating, its what they're eating. First and most important thing you need to do is boost their immune system. So feed them high quality foods that are high in protein and Omega-3 fatty acids. Soak the food in a product that contains EPA and DHA Omega-3's. Selcon or Zoecon will do. I recommend soaking live brine shrimp is Zoecon for 24 hours, then turn all the pumps off when feeding so that the fish will have a chance to eat Zoecon covered live food. You may also try soaking food in garlic product that is high in antioxidants. You can also try Frozen Cyclopeeze which is naturally high in Protein and Omega-3. Also you can use a product like Purigen, throw a bag of this in your sump tank and your nitrates should go down to 0 in a 2-3 days. I hope you have a good skimmer to get all the organics out. Do a water change if needed. Once the immune system is up again, [STRIKE]they will never get Ich[/STRIKE]. Continue to use high quality food and maintain good water conditions. I've brought home sick fish with Ich and brought them back to full health. None of my other fish ever got infected.
