so recently my male betta fish has (i think) an opened wound on the side of his body. I was changing his water last week when i noticed it and there was a few drops of blood in the container I had him in prior changing the water. I have been using betafix and changing 1/4 of the water to keep the tank/water clean but the wound has grown a bit bigger, im not sure if its a fungus/ infection. My betta still swims around and is blowing bubbles in the tank, but he chills near the heater/filter and lays on his side. However, when he swims he does seem to struggle a bit and does sink. Pictures are attached below.
