and this is what it said
Don't Get Rid of Those Little Red Wigglers...
...FREEZE DRY THEM!
Don’t be alarmed if you find little red worms in your filter material. They are nothing but harmless blood worms, the larvae of the midge fly. They are a very natural occurrence in the pond and, although they aren’t very attractive, are okay to feed your fish. After all, once freeze-dried, this blood worm becomes what marketers call "Tubifex Worms". They’re packaged and sold in pet supply stores as a fish delicacy.
Oh, and don’t start measuring how "dirty" your water is by how many worms are in your filter. Blood worms are found in "clean" water.
thank marsia you always have the answers
