My husband keeps three arhat fish. Will earthworms parasitize us? Or is bacteria harmful to human body? .

No, the water earthworm is an aquatic animal, not a parasitic animal. Without water, it will die.

If you feel disgusting, you can ask your husband to buy frozen red blood worms for fish. The nutritional value is higher than that of earthworm, and the price is a little higher. (Of course, there are also live ones)

In addition, if you are very picky, you can buy beef heart and shrimp meat, chop them together when you come back, then ice them, shape them and feed them. This is top food.
