I have a small 20litre tank and im almost at the end of my fishless cycle

My question is will these two small sea shells i put in there cause problems

I washed them in hot water and they sat outside in my room for a few months before I put them in.

I've had numerous seashells, collected at the beach, in my tanks for years. You did the right thing. A good wash in hot water. Maybe a hard shake to dislodge any leftover sand grains if you're worried about old sand. But they'll be fine anyway.
