Help your fish fight Ich!
Stressed fish are more susceptible to Ich infestations. If the aquarium has too many fish or ammonia and nitrite levels are always detectable, your fish are stressed! Fish can fight off Ich through a specific immune response. Reduce the number of fish or get a larger aquarium. This is the only way to eliminate the problems created by overloading the tank with fish. .
