Ok so I was admiring my bichir tank and my delhezi was laying at the front of the tank. I took a look at him and notice some strange markings on his head. It looks like a cross. Is this normal? I have never seen him with that mark before. It looks kind of cool but I'm worry if he would be alright.
Here are some pictures of the cross, sorry for the blur images
