This is my first time owning a puffer and I am not quiet sure what their beaks are supposed to look like. I do know with almost all puffers you are supposed to feed them shellfish so their teeth dont overgrow but I was wondering if my puffer has a mouth fungus or is that just the way his mouth looks as a juvenile. This one is a Figure 8 juvenile puffer i believe.
