Water changes once a month, will not do for 10 gal tank holding a pleco of near any species with exception of Pit Bull pleco possibly. Water changes for nearly all tanks should be on the order of 25 percent weekly.
Usually ,sores and fungus are associated with secondary bacterial infections which are related to declining water quality. I might try performing water changes more frequently,providing prioper foods for the pleco. Some are herbivores,some are omnivores,and some are carnivores. If it is common variety,alage wafers and fresh vegetables such as zuchinni,spinach leaves,lettuce,etc can be offered. Common variety pleco will quickly out grow the ten gal and be a constant source of water quality issues due to large amount of waste produced.
suprised you didnt go further with the water quality issue :P
going to agreer that the illness was brought on with poor water quality and minimal w/c's spcially for a pleco in such a small tank. if i were you i would continue the treatment then when it clears up treat for a week or so more and keep a eye on nitrites and ammonia since the treatment will destroy the BB. i would even recommend a Q tank to treat in. during this treatment your tank is going to have high ammonia and nitrites dont add any fancy ammonia or nitrite removal chems just test everyday and change up to 75% of water to get parameters where they need to be and re dose meds accordingly.
