I have a cannister of brine shrimp treats flake food from Tetra. I noticed recently that there are a bunch of tiny insects in it, white and light brownish looking, smaller than ants. I'm wondering you guys think they are harmful to the fish and I should throw the whole thing out, or if the fish would enjoy eating them? I have no idea where the insects came from, except that maybe they went in at a time when I didn't close the cap right away...
