I had 7 ghost shrimp in my 5.5 gallon tank that I bought about 2 weeks ago. This is my first time keeping shrimp, but I noticed one had a white string inside it. I didn’t know what it was, so I left it alone. I found it passed away yesterday and the white string was gone. I just found out today that it was actually a horse hair worm! It’s already left the host, and after doing some research I learned that it leaves the host to breed. I have other shrimp in the tank and I have no idea how to get rid of all the worms and possible babies before it’s too late. I want to add a betta into this tank eventually, but I want to treat the tank and my shrimp first. I looked around the tank and can’t seem to find any worm. What should I do?
