Are these copepods on the glass? The clip will expire in a couple days but just verifying it’s not ich or planaria or some parasite I need to get rid of (My yellow clown goby occasionally swims crazy up against the glass like it’s scratching itself). The tank is two months old. I had a week or two of aggressive growing diatoms, cleaned it off last week and realized this week it doesn’t seem to be growing back. Also my tank glass has been unusually no-maintenance this week of film algae, except for that one spot in the clip.
