Water Gardens — Tubifex worms

I HAVE a lot of what appear to be red worms living in the sludge at the bottom of my pond. Are these harmful and, if so, what can I do?


THESE are most likely Tubifex worms. They are actually harmless - in fact, they are very good fish food, as keepers of tropical fish will tell you.

However, as they grow in organic sludge and feed on what you and I would call sewage, they tend to indicate that it is time for a clean out.

Winter is the perfect time for this unpleasant activity and as an added bonus, all the murky sludge you remove is great for the compost heap.
