Could you test your water for amonia nitrites and nitrates in your lfs? Bad water quality is probably the issue...

If I were to change all the water, would the situation improve?

Nope. You'd just kill the benefiticsl bacteria in the filter, and you would need to cycle the tank again (if it's cycled). Daily 50/100 water changes could help, though. Prime would also help. IF the tank is not cycled. But we can't know that, without the water parameters...

I’ll get a testing kit, thanks.

So, I did the test - both NO2 and NO3 are zero.

Can you post the photo as a thumbnail so we can enlarge ourselves? Or focus on him to the white area is more clear? Thank you.
