Ich, pronounced "ick", is an external parasite often referred to as "white spot disease." Aquarium fish develop Ich due to stress or improper aquarium conditions. Most often, it is brought on by fluctuating aquarium temperatures.
Hole-in-the-Head Disease
Primarily affecting cichlids and also known as Head and Lateral Line Erosion (HLLE) or Hexamitiasis, this condition is still poorly understood. Many believe the causes are poor water quality and a lack of vitamins A and C.
How Fish Food Quality Affects Water Quality
Quality fish foods help prevent the types of water problems that can result from foods with undigestible ingredients.

Avoid common mistakes that result in unnecessary fish loss. Make smart choices and ensure aquarium success by learning how to select healthy aquarium fish. Before you buy new fish, consider the following.
Quality Fish Foods for Healthy Fish

Prevent costly losses by having a quarantine tank ready for any unexpected event. Use quarantine tanks to monitor new aquarium inhabitants before adding them to your main aquarium.
Quarantine Tanks: The Benefit of Aquarium Kits

The Dangers of Overfeeding Fish
Overfeeding fish is so easy to do. First, we forget how small they are: our appetites are much bigger than their stomachs! Second, feeding is one of the only ways we can interact with the fish, so we tend to do it too often.
The Importance of Aquarium Vitamins
Fish need vitamins for health just like any animal. An improper or incomplete fish food diet can result in nutrient and vitamin deficiencies and the onset of serious conditions such as stunted or improper growth, a weakened immune system, or death.
The Importance of Nutritional Variety
A varied diet is important to maintain good nutrition and the well-being of your fish. Offer supplementary foods in addition to the "staple" diet for better nutrition and to enrich the diet of your fish with greater tastes and textures.
Tropical Fish Parasites, How to Identify
The most common parasite in both fresh and saltwater is Ich (Ichthyophthirius multifiliis) or white spot. Others frequently found include Anchor Worms, Black Spot, Costia, Gil Flukes, Hexamita, Fish Lice, and Velvet.
Understanding Aquarium Fish Nutrition
Proper nutrition is essential for healthy aquarium inhabitants. Achieving good nutrition is more than choosing a food and feeding your fish. When selecting food for your fish, consider the dietary needs of all your fish.
Water Temperature & Ich Prevention
A sharp drop in water temperature is extremely stressful to fish and can compromise their immune system. Improperly sized heaters may not be able to maintain their set temperature and cause aquarium temperature to fluctuate several degrees per day.
What's That Smoke in My Aquarium?
Most likely, high levels of ammonia have recently been experienced by this tiny eco-system. This causes nitrifying bacteria that consume ammonia to reproduce so quickly, they over populate to the point that they are visible.
