Is it a parasite?? On Glass

.....oooooo looks nasty lol

 

yeah those are definetely flatworms. I just treated a tank with flatworm exit. It took several doses to kill them all. Make sure you follow the directions very carefully and siphon off as much as possible prior to treating. Once they die they release toxins into your water so you want to get rid of as many as possible before you treat.

 

Yup Yup, read the directions and be prepared to do a decent water change.
Do not treat until you have manually removed as many as you possibly can.

 

This link was perfect, Thanks for everyones assistance. i will update as I go. 180 gallon tank so I have a huge task ahead.

I also went and bought a sixline wrasse today too. He went to work right away!!

 

Sixlines are a little mean, but anything to do the job.
