Some how they must have been introduced ...The garden is about 600 gallons and holds about 20 goldfishes. Will the fish eat them or will the leeches feed on them? And should I do anything about it? Thanks
I found in my water garden a couple of small leeches...
I would not worry about them if they are just the small reddish ones. After buying plants and fish, I found one in my water garden too. The lady at the fish/plant place told me they are normally terrestial but will find their way in one way or another. Just what I was told.
