The grass goldfish, also known as the golden crucian carp, is the ancestor of the goldfish. The grass goldfish has a strong constitution, strong resistance and adaptability, and a wide range of food habits. But many friends don't know what grass goldfish eat, and how to buy goldfish feed? Today, Xiaobian brings you the knowledge related to grass goldfish diet.

What do grass goldfish eat?

Grass goldfish have a wide range of food, generally 1 animal bait contains Daphnia, Daphnia, rotifers, protozoa, water worms and minced meat of fish and shrimp, etc.; artificial food, fish meal, blood meal, egg yolk, silkworm chrysalis; Bread crumbs, rice grains, grass leaves, etc.; are the best food for grass goldfish.

Selection principle of grass goldfish feed:

1. Good smell, good feed has a natural fish and shrimp fragrance, while poor quality feed adds a lot of flour, smells like A greasy spice smell, and a salty feel, a bit like MSG or chicken essence. As for the kind that smells sour or rancid, it's the worst.

2. No muddy water, good feed can keep the prototype for a long time in the water, and will not fall apart and dissolve. Poor quality feed will soon become mushy, and even the water will turn into the color of feed, that's too bad! Of course, this long time is a matter of opinion. There is a saying on the Internet that it is a day, but I personally don't agree. Because if the feed does not dissolve in the water for a day, it will be similar in the stomach of the goldfish. How difficult is it to digest? Therefore, the feed that does not dissolve for too long may cause enteritis. I personally think that the feed can be kept in the water for 2-4 hours without interference. In fact, it is better to feed the goldfish within 3-15 minutes. By the way, many places that sell small goldfish are 50 cents per bag of red and green two-color small-granule bulk feed, red blood red, green emerald green, that is super rotten, muddy water, faded color, don't buy it!

3. It is not greasy, good feed is put into the water, and the water is still clear, just like no feed. The poor quality feed itself has insufficient materials, in order to lure goldfish to eat, oil is used to enhance the fragrance. The surface of that kind of feed looks shiny and shiny, and when you get into the water, the surface of the water is a layer of oil film, which is horrible to see, and maybe it is still using waste oil.

4. Small size, the online saying is that the feed should match the fish, the big fish should be fed the big feed, and the small fish should be fed the small feed. But I personally think that the feed should be one size smaller than the fish, that is, the big fish are fed with medium grains, the medium fish with small grains, and the small fish with ultra-small grains. The reason is, of course, that the smaller the feed, the easier it is to digest, reducing the chance of losing the swim bladder due to enteritis. But if it is too small, the eating time will be prolonged. The fish eats hard for a long time, but there is nothing in the stomach, which is not very good, so a smaller size is better.

5. It does not swell when exposed to water. After a good feed is put into the water, after a period of time, the volume is almost the same as when it is dry. And poor quality feed, water swelling is very strong. Everyone knows that goldfish actually know that they are full, but some goldfish are still killed. In fact, they have eaten inferior feed. It is no problem when they eat it, but the feed quickly absorbs water and expands in the belly of the goldfish. Even if it does not die, it may endure indigestion or even enteritis.
