So as the topic says, my sleeper goby has developed deep wounds on its either side of its face. There's nothing in the tank that would be attacking it - He's at least 10 inches long and the only other fish in the tank are 2 silver sharks, and a common pleco. these wounds are getting worse and im worried he might die. Here are a few pictures, I apologise for for the poor quality.
This is what he looked like before the wounds.
His left side.
His right side.
I appreciate any help on what might be causing this, and how to cure/prevent it. Thanks
