Oh, about swabbing the area, if you can catch the fish without to much strees a swab with hydrogen peroxide can help, but in this case I wouldn't, te infection is still very minor and you risk injuring the fish during capture.
Yeah i decided not to swab the infection. Right now he is a 10 gallon tank, with a sponge filter and an airstone. I have added salt a little bit at a time, till I reach the correct amount to put in.. The pleco is swimming around.
Thanks for all of your input
