I have received my fish food order today, I ordered some bloodworm pellet from a different supplier because I noticed on my last batch some sharp bristles sticking out of the pellet, I pulled a couple out and they are like toothbrush bristles. The bloodworm pellet I have received today has the same things sticking out. I dont know whether this is normal and I have just never noticed before, or there is something wrong with both batches?
