After watching my 5 goldfish tonight I noticed that one of my newer goldfish had something sticking out of the side. Upon forther research I believe it to be an anchor worm. My book says to pull it gently out with tweezers. swab it with mercurochrome. then apply long term pool treatment of metrifonate at 0.25-0.5 ppm
or 1-2 per 4000 l of pool water every two weeks for six weeks with pool water at 18-20 C or more.
This raises several questions. First what is the best way to take a fish out and remove the anchor worm? I will go out and buy the necessary meds but are these the correct meds I will need? Also, when I treat the fish do I treat the whole tank? Is this going to spread to my other fish? The area does not seem red or very infected so I am hoping it isnt too bad.
Also, I have a 75 gallon tank with 5 goldfish. My ph
is 7.5, my ammonia is 0, and my nitrates are 0. Can someone put it in simple terms how much meds should i give?
