I see copepod, fluke and possible turibella worm. Freshwater dip should address the flukes and any worms.

Which is the fluke? The red one #10? The worm #12? And copepod I'm not sure.

And this is the brown stuff on my sand... Idk what it is, was thinking diatoms but not sure.
I did some research...but can't seem to find these...

I am sorry can you circle where the fluke is, I'm assuming it's the big thing but...I read a post and used Google lens and I'm just not seeing it. Maybe the species of the fluke would be helpful to me.

Not harmful?

 

[Kristopher Conlin]

Not harmful?

It can be if the population explodes. they can release a toxin. Do you have a lot on the sand?

12 nematode maybe. Hard to still see others. If you have bigger bacteria with hair like structures and movement some sort of cilliate.
