They are always asking about leaves. After the leech episode with 2 turtles from the same lake, I said no. I guess, I can get the leaves and soak them in saltwater, then use them. Saltwater kills leeches on contact. Thanks for the suggestion! knifegill;4208388; said:Oh, that's easy! Gather fallen maple leaves (find solid, thick ones) and gently bake them. Then give them a rinse, maybe a pre-soak and you're good to go. I've got them in four tanks and my catfish LOVE them.
