It is best not to raise goldfish in grass tank. First of all, goldfish are omnivorous fish, and there are many kinds of food that can be eaten. When they are hungry, they will eat aquatic plants to satisfy their hunger. After the aquatic plants in the grass jar are eaten by goldfish, they will lose their ornamental value. Secondly, the metabolism speed of goldfish is relatively high, and their food residues and feces are easy to fall into the mud of aquatic plants. Aquatic mud can't be cleaned, but if it is not cleaned for a long time, bacteria may breed.

Finally, aquatic plants need enough light to grow better. Although goldfish also need sunshine, the light time should not be too long, otherwise too much discomfort may occur. Although goldfish is not suitable for breeding in grass tanks, it is ok for breeders to insist on breeding. It is only necessary to ensure that they have enough food when breeding, so as to avoid eating aquatic plants.

goldfish eat aquatic plants, their feeding habits are miscellaneous, and they can eat more food. If they are put in a fish tank where aquatic plants are raised, they are likely to chew them clean.

Although goldfish will eat aquatic plants, they will not eat all aquatic plants. There are some aquatic plants with large or hard leaves, which can't be eaten. If breeders want to place some aquatic plants in goldfish tanks, it is best to choose some aquatic plants with hard leaves or large leaves, so as to avoid them eating aquatic plants.
