My giant gourami has a bruised looking spot on his side. I just want to double check that its a simple injury as he has injured himself on the driftwood in the past, though has never created a bruise. I have attached a few pictures. Please take a look and let me know if it's something i need to treat or simply let heal. As a note the scales are a little lifted. I figured this could be due to inflammation. I just want to make sure it's nothing else that's aggravating his scales and causing a bruised look. Thanks.
