Looking up your tank data…
NO3 40 ppmpH 6.86× neon tetrawater change 5 days ago
Your NO3 jumped to 40 ppm (last measurement 2 days ago) and you haven't done a water change in 5 days. This is the most likely cause. I'd suggest a 30% water change today and retest parameters tomorrow.
Could it be my filter?
Unlikely as the primary cause — you cleaned the sponge 2 weeks ago and flow looks fine in your log. Start with the water change; if nitrates come down but behavior doesn't improve, we'll dig into the filter next.
