Hi Echoma and welcome to the forum. From the pics, it looks like your bristlenose pleco has a huge open sore on his back?
Can you describe the symptoms and any kind of treatments you have used?
Also, what kind of tankmates does he have?
Unless you are keeping discus, you may want to turn the temp down to 76 F or so, as the temp is pretty high even for tropical fish. At that temp, the oxygen levels in the water diminish and the fish have trouble breathing.
