I hope that you also got my PM. My advice falls pretty close in line with what Aquanero posted . I did not realize you had other fish in the tank and understand your conern. As stated a hopsital tank or other tank to put the pleco in is an option. I am not sure how big he is but if you are really concerned you can also try to get a 10gal tank off craigslist or a larger critter keeper from the dollar store or something and put an aerator in it or a sponge filter for temporary purposes if you don't have an extra tank (I have had to do this before)- you can get that when you run out to get your meds. Just a thought
