I've had my Spathiphyllum wallisii for about four months now, and I'm still figuring out the watering rhythm

I've had my Spathiphyllum wallisii for about four months now, and I'm still figuring out the watering rhythm. It droops dramatically when thirsty, which is honestly helpful feedback, but I worry I'm either overwatering or letting it dry out between drinks. It's one of nine plants in my tropical setup, and the others seem easier to read. Has anyone else found peace lilies particular about their water schedule, or am I just overthinking it? I'd love to hear what's worked for you.
