Do You Want Healthy Looking Fish?
Needless to say, all aquarists want their fish to have bright eyes, strong fins, and healthy gills. In order for fishkeeping hobbyists to achieve that, 3 things must happen. You have to…
- Provide your fish with enough nutrition
- Keep your fish digestive systems in order
- Fortify your fish’s diets to keep them in tip-top shape
Provide Fish With Enough Nutrition
The fear of overfeeding or concern over water quality may cause fish hobbyists to underfeed their fish.
When fish are bred on a poor diet, they tend to suffer from nutritional deficiencies. This weakens their immunity to parasite—and bacteria-related disease. A weakened fish may never recover, even if improvements are made to the diet later on.
In order to sustain the long-term health of your fish, it is necessary for you to understand the dietary requirements—the types of food and the number of feedings—of the particular species you keep.
Keep Fish Digestive Systems In Order
Fish can be given an occasional feeding of vegetables such as lettuce, kale, peas, spinach and broccoli.
While these vegetables do not provide worthwhile nutritional value, they help add fiber to the fishes’ diets and keep their digestive tracts clear.
On the other hand, some of these vegetables are very high in cellulose, which can clog the digestive tract. Others, like spinach, contain oxalic acid which can cause crystals to form in the kidneys.
Break down the cellulose in these vegetables to help your fish digest them. Prior to feeding Iceberg or Romaine lettuce, blanch the vegetable in scalding hot water for about 30 seconds. Alternatively, you can freeze it, or microwave it for about 15 seconds.
Fortify Their Diets To keep Fish In Tip-top Shape
Many flake foods contain a variety of ingredients such as algae, beef heart, liver, fish meal, yeast, tubifex worms and shrimp meal.
The colors of the flakes are fairly good indicators of their nutritional value. Red promotes coloring and spawning, yellow encourages growth, and brown enhances resistance to disease.
One particularly nutritious flake food for herbivores is spirulina. This macro-algae is high in protein, beta-carotene, vitamins ad minerals, and is a natural antibiotic that helps improve the fishes’ survival rate.
Another form of nutritious algae feed is dried Nori seaweed, which usually comes packaged in paper-thin sheets.
As they have undergone processing, the nutritional value and taste of dried and freeze-dried foods are not as good as fresh, live foods. Similarly, the amino acids in frozen foods become altered when they undergo the freezing process. Vitamin (e.g. Vitamin B and Vitamin C solutions) and mineral additives can be included in these foods to enhance their quality and taste.
You are what you eat!
However, our fish solely depend on us for their great health and vibrant nature. So be watchful of what you feed them with!
