Usage and Procedures

Application 1: Custom-designed micro-particle floating feed. Ornamental fish have small mouths, so feed particles cannot be large. Aquaculture equipment can be equipped with ultra-fine 0.8mm molds to produce micro-particles resembling small green beads. Simultaneously, by increasing the expansion temperature to 130℃, small air bubbles form inside the particles, causing them to float on the surface. This makes it easy for ornamental fish to peck at the food and allows owners to clearly see the feeding process, increasing interactive enjoyment.

Application 2: Evenly distributed natural color enhancers. The body color of koi and arowana is a key aesthetic feature. The feeding system of aquaculture equipment can precisely add natural color enhancers, such as 5% spirulina powder or 3% astaxanthin. These ingredients are evenly distributed in each feed pellet by the equipment's mixing system, resulting in more vibrant body colors for the fish. This is safer than using chemical color enhancers and will not harm the fish.

Application 3: Precise control of low-pollution formulas. Aquariums are shallow, and feed contamination can easily cause the water to become cloudy. Aquaculture equipment can adjust the humidity of raw materials and the expansion parameters to make the feed pellets compact and resistant to soaking. They can stay in the water for 2 hours without breaking apart, reducing the pollution of water quality by feed residue. This eliminates the need for frequent water changes, resulting in clearer aquarium water and a better viewing experience.

Maintenance Precautions

Making ornamental fish food using a floating meal extruder machine can save up to 40% on costs compared to buying dedicated ornamental fish food, making it especially suitable for aquarium enthusiasts who keep many fish. Natural color-enhancing ingredients make the fish's colors brighter; for example, koi's red becomes more vibrant and their white more pure, increasing the fish's value by 20%-30%. At the same time, the low-pollution food stabilizes the aquarium water quality, making the fish less susceptible to fungal diseases and enteritis, significantly increasing their survival rate. This eliminates the need to frequently buy new fish, saving both money and effort.
