A well-designed formula ensures optimal growth and health.<\/p>\n\n\n\n<p><strong>Pellet Size<\/strong><br>Different fish species and growth stages require different pellet sizes. Small pellets are suitable for juvenile fish, while larger pellets are used for adult fish.<\/p>\n\n\n\n<p><strong>Water Stability<\/strong><br>High-quality fish feed should maintain its shape in water long enough for fish to consume it without disintegrating quickly.<\/p>\n\n\n\n<p><strong>Floatability<\/strong><br>For floating fish feed, the pellets must have good buoyancy to stay on the water surface.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"768\" src=\"https:\/\/dayiextrudermachine.com\/wp-content\/uploads\/2026\/02\/52bd088ea99af94f3322fda8d5a6dc34-1024x768.jpg\" alt=\"\" class=\"wp-image-6888\" srcset=\"https:\/\/dayiextrudermachine.com\/wp-content\/uploads\/2026\/02\/52bd088ea99af94f3322fda8d5a6dc34-1024x768.jpg 1024w, https:\/\/dayiextrudermachine.com\/wp-content\/uploads\/2026\/02\/52bd088ea99af94f3322fda8d5a6dc34-300x225.jpg 300w, https:\/\/dayiextrudermachine.com\/wp-content\/uploads\/2026\/02\/52bd088ea99af94f3322fda8d5a6dc34-768x576.jpg 768w, https:\/\/dayiextrudermachine.com\/wp-content\/uploads\/2026\/02\/52bd088ea99af94f3322fda8d5a6dc34-1536x1152.jpg 1536w, https:\/\/dayiextrudermachine.com\/wp-content\/uploads\/2026\/02\/52bd088ea99af94f3322fda8d5a6dc34-16x12.jpg 16w, https:\/\/dayiextrudermachine.com\/wp-content\/uploads\/2026\/02\/52bd088ea99af94f3322fda8d5a6dc34-600x450.jpg 600w, https:\/\/dayiextrudermachine.com\/wp-content\/uploads\/2026\/02\/52bd088ea99af94f3322fda8d5a6dc34.jpg 1702w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">6.
