I know we've been through this not too long ago, but I recently noticed the "white stringy feces", indicating an internal parasite, once mentioned on the list several months ago. I found a source for Levamisol HCL at a local feed store and was able to purchase a single horse (Sheep) pill (1.8G) for a dollar, under the name "Tramisol". My question is, what is the recommended dosage for a 55 gallon tank, and how should the substance be introduced to the water? Thanks for the help in advance!
