Thanks for all reply.
It's definitely a slime mold. Don't know anything about farming shrimp, though the pictures look real interesting, but could it be the food that you're feeding them is infected? If the shrimp do not eat it very soon, it will spoil and form that fungus.
Slime mold is a great keyword for me in this situation. Thanks so much. I hope this mold is a aquatic species. I had managed my water carefully as i can but not paid attention to my shrimp feed. My shrimp had gotten disease after it appeared. Maybe the shrimp ate them?
Maybe your aquarium needs a partial water change. It probably has a bacterial buildup, and not all bacteria are good. Clear water is a good sign, but it's not the only indication of a healthy aquarium.
By the way, those shrimp are so cute
The shrimp was really cute but had died

In the shrimp pond, change water is the big problem because of high expense and shocking or maybe get pathogen from outside water into pond.
Why not vacuum the mold out as soon as you notice it growing?

True. A clean tank with no excess nutrients will not grow fungus.
It a shrimp pond, not a aquatic tank and i do not know how to vacuum something from it.
And this creature develops very very fast that i can not control immediatly. After one day it occurs, it spreads all my canvas and the shrimp be sick. But your reply is a good idea for me to remove nutrient in water. Thanks so much.
