Could someone please help me with a little problem. One of my Caribe has a large bump on his mouth from rubbing/hitting the glass a lot. The other one has the same thing buy then it looks like he has blisters on his face and the side of his head. Just white patchy spots. It may be from rubbing on the tank or it may be some fungus or something. Please tell me what I should do. Also, sorry I couldn't get the pics in the post but I'm not sure how to put them in here without attaching. Again, please help and thanks.
