Vitamin Deficiencies

Okay it's not really a disease, but the symptoms can often look like it...

This can also cause abnormalities similar to TB and Genetic defects. Lack of Calcium and Vitamin C are the two main culprits, resulting in bent spine and abnormally small fish.

Online Diagnosis

What to Look For

  • Scoliosis (Curved Spine)
  • Reduced Growth
  • Anorexia (Lack or Loss of Appetite)
  • Low fish weight
  • Lethargy

What's going on?

The lack of essential vitamins and minerals in the diets of freshwater and saltwater fishes and invertebrates can lead to health problems, a common one in fish being head and lateral line erosion disease.

How to Fix It?

The only treatment is to practice good fish keeping care. Below is a slated plan for what every tank keeper should do.

If you have a fish that you think might be a victim of Vitamin Deficiency, follow the below plan step by step:

1. Weekly feed your fish a minimum of 3 different types of food. (Example: Oscar Cichlid gets tropical flakes and floating cichlid pellets daily, once a week frozen blood worms are given.

2. Do Weekly 20% water changes accompanied with gravel washing.

3. That's it that's all you need to do to promote good fish health.

How to Prevent this?

Feeding your fish an improper diet is as common a mistake as overfeeding.

Providing the correct diet is essential for fish growth and health. Dietary deficiencies will not only shorten the lifespan of fish and cause many diseases, but will also contribute to a deteriorating water quality by polluting the water.

The diet of fish varies based on their individual nutritional needs. Some require meaty foods (carnivores), some plants (herbivores) and some a combination of both (omnivores).

Protein is necessary for growth and for repair of cells and body tissue. Proteins must be supplied regularly to ensure good growth and health. It is the most expensive component in feed and may comprise anywhere from 25 percent to 55 percent of the diet, depending on the fish species and size. While it is an important source of energy, excessive protein will simply increase ammonia production. Fish and shrimp meals are common sources of protein in fish feeds.

Lipids (fats and oils) are important to fish since they provide energy and allow the uptake of fat-soluble vitamins and other crucial nutrients. They are available from many sources, and extra fats can be stored in the body. Too much fat can affect the liverís ability to filter and cleanse the blood.

Like fats, carbohydrates provide energy for body functions. However, only omnivores (meat and plant eaters) and herbivores (plant eaters) utilize carbohydrates well; carnivores (meat eaters) do not.
