he acts like he wants to eat and he will hit the live gold fish but he doesnt swallow it he has been doing this for about a month he just holds them in his mouth he occasionally swallows one but its like he is having trouble swallowing them. he is also 13 inches long and the gold fish he eats are between half inch to inch, i have been thinking he has a mouth fungus or something so i started treating him with fungus guard 2 days ago... if anyone can help pls im not tryna lose this guy he has some of the nicest markings i have ever seen.
