Optimal nutrient dosage helps the fish to stay in their physical prime. These nutrients consist of vitamins, minerals, lipids, etc. You can supply it naturally with food, i.e., broccoli, shrimps, etc., or as a by-product, e.g., aquarium salt, installation of coral reefs, etc. This article will discuss the nutrients and the best fish food vitamins and minerals.

What Nutrient Do Aquarium Fish Need The Most Of
Fish have different eating preferences, such as carnivores, omnivores, and herbivores. They have evolved according to their dietary choices. However, the basic nutrients are the same for all fish: proteins, lipids, carbohydrates, minerals, and vitamins for fish food.
Protein
Protein is one of the most important parts of fish food. It helps them grow and repair tissue. The requirement varies among species, i.e., from 25 to 55%. Carnivores have a higher demand than omnivores. Other than type, protein dose varies according to size and specific species.
Lipids
Fat and oil or lipids are other necessary parts of fish food. Lipids are the powerhouse for fish and help them to absorb fat-soluble vitamins. Despite its importance, fish food contains a small proportion of lipids. Lipids dietary level varies among species. For example, 9 to 12% is the optimal level for hybrid pufferfish.
Carbohydrates
Sugar provides energy for respiration. Fish can store excess carbohydrates for later usage in their liver and muscles. Unlike lipids and protein, there is no concrete ratio of carbohydrate levels for fish growth.
Vitamins
Vitamins are another must-required nutrient for fish food. Each vitamin serves an important role in fish food. Vitamin C is one of the most required, as the fish body can’t make it by itself. Vitamins A, D, E, K, D2, D3, E, K, B6, B12, Thiamine, Riboflavin, Pantothenic acid, and Niacin are other important vitamins for fish growth.
Minerals
Minerals play a pivotal role in fish growth. They help in growth, development, and physiological state. Zinc, iron, copper, calcium, sodium, and chlorine are important dietary minerals for fish growth. Each species requires a distinctive mineral dosage.

Which Vitamin Is Best For Fish?
Every vitamin in dosage is the best for fish growth and health. However, vitamin C has an edge over the rest as fish can’t make it themselves. Here is the importance of different vitamins, their roles, and their relationship with fish growth. Moreover, food sources and importance are also part of the discussion.
| Vitamin | Role | Growth Relationship | Food Source | Importance |
| Vitamin A | Supports vision | Necessary for skeleton development | Fish liver oil | It maintains a strong immune system, enhances growth, and improves the scales of the fish body. |

Minerals Do Fish Need In Water
Fish require numerous minerals in fish food and water. These minerals are classified into 2 categories: macro minerals and micro minerals. Fish intake these minerals from food or absorb them from water via gills or skin. Over-macro or under-mineral levels are toxic for fish health. There should be a good balance to maintain homeostasis.
Macro-Minerals
Fish requires the following in big doses.
| Calcium | Magnesium | Potassium |
| Phosphorus | Sodium | Chloride |
Micro-minerals or Trace Elements
These minerals are required at a minute level.
| Cobalt | Iodine | Manganese | Zinc |
| Copper | Iron | Selenium |
As mentioned, fish can intake minerals from tank water. Here are some such minerals in fish food, their importance for fish, and their role in a fish tank.
| Mineral | Role in tank | Importance for fish | Sources |
| Calcium (Ca) | Regulate water hardness | Avoid deformities | Crushed coral |
| Improve skeleton | Aragonite | ||
| Help in muscle contraction. | Limestone | ||
| Water conditioner | |||
| Magnesium (Mg) | Regulate water hardness | Support enzymatic reaction | Dolomite |
| Maintain pH | Support energy metabolism | Marine salt | |
| Natural mineral additives | |||
| Potassium (K) | Regulate osmoregulation | Maintain electrolyte balance that helps fish avoid stress | Plant fertilizer |
| Regulate cellular function | Muscle function | Potassium salt | |

Add Vitamins And Minerals To A Fish Tank Naturally
The addition of vitamins and minerals is not something you can do by introducing some special substances in the tank. You can achieve it naturally. Here are some natural ways to add minerals and vitamins to a fish tank.
- A small quantity of tap water.
- Add Good fertilizer that contains micronutrients.
- Liquid fertilizer for aquatic plants
- Introduce coral, cuttlebones, and eggshells to increase calcium additives.
- A small quantity of garlic.
- Seaweed or algae for herbivorous fish.
- Feed your fish on fresh vegetables and fruits.
- Sunlight exposure by placing it near the window.
- Offer fermented food.
- Feed on live or frozen food for vitamin B-complex and E.
