Aquarium Advice Regular
I also have a tank with some goldfish. I find that with goldfish you don't need any other "cleaner" fish. Mine will eat algae, snails you name it. I just wish gold fish didn't grow so big. Since you found the leeches sucking on your fish then they are a true problem for the fish. My leeches lay eggs as you describe in brown sacks that or nearly indestructible.
Wish you the best of luck
