Ok. I got bloodworms then as time pass by without the bloodworm getting finishes because my aba knife is just 4". It turned black then i accidentally fed it few but not sure wether he ate it but im really worried, is something bad gonna happend? Ive obsered it this evening but nothing went wrong so i think he didnt ate it. Whats the cause of this blackness? Is something gonna happen to my fish?
