Howdy folks, I noticed that my female Madagascar Rainbow has developed something on top of her head. The fins appear to be split open and now a fleshy-substance is beginning to come out. The wound appears to be growing. She is not in stress, has an appetite and swims around just like she always has. The other fish are not picking on her or the wound, and I've watched for a long time to make sure that wasn't happening. My guess is that this is some sort of hemorrhaging, although I have no idea what could have caused it other than maybe getting a little too excited during feeding time and jumping out of the water and hitting the bottom of my hood. Any thoughts on what I could/should do? Thanks!
