Feeding Live Food

The choice to feed your ornamental stock with live food, instead of dry manufactured feed, is mainly determined by the growth stage of the fish. Newly hatched fish desires food of a very small size due to their jaw size and the immaturity of the digestive system during the early stages of life. Live foods, such as brine shrimp and mosquito larvae, that are readily absorbent, meet these requirements and provide the high-protein needs of larvae. However, do not rush to serve live food as the first meal. Generally, after a fish hatches or a fish gives birth they have what is called a yolk sac, which will be absorbed in approximately 2 – 3 days. After this time, live food can be given.

Live foods are highly nutritious sources of micro and macro nutrients, vitamins, fats, proteins and carbohydrates and contribute significantly to increased growth rates. The use of live foods simulates the natural eating environment for captive aquatic life, making the stock more vibrant and colourful.

Furthermore, live food is an excellent conditioning agent for brood stock.  Its high nutrient concentration encourages spawning activities; hence increasing your breeding success rates.
