How to grow fast in koi, the cause and treatment of oblique tube worm in brocade carp
The damage to the skin and fins is mainly in the seedling stage.
In addition to invading the skin, the adult fish invades the gills, oral mucosa and nostrils at the same time.

In severe cases, the fish body emaciated and blackened, floated on the water, or stopped in the leeward of the fish pond and died.
The dead diseased fish had more mucus on the body surface, the Gill filaments were reddish and the Gill filaments were thick.
The suitable temperature for reproduction of oblique tube worms is 12 ~ 18 ℃. It can still occur in large numbers when the water temperature is as low as 8 ~ 10 ℃, but it is not easy to occur when the water temperature is above 28 ℃.
