Quote – Holmes on ‘Entomology’
” I suppose you are an entomologist ? “
” Not quite so ambitious as that, sir. I should like to put my eyes on the individual entitled to that name.
No man can be truly called an entomologist,
sir; the subject is too vast for any single human intelligence to grasp.”

These algae are present in my pond-water aquarium. Surprised you don't have similar species. Algae are very common in F/W. My 977 pages book of just the western Great Lakes mentions 1,300 species exclusive of desmids and diatoms (Closterium is a desmid).
The crystals are Barium Sulphate and they may be used as statoliths.
Statoliths help in letting an organisms know which way is up.

I recall experiment with crayfish where the sand statolith was replaced with a tiny piece of iron. Worked fine until the researcher placed a magnet at the side of the tank; the crayfish then figured that the side was actually the bottom and orientated themselves sideways.

I would love to find some algae. I believe I have seen one Desmid, but it was in bad shape and very small. I was after something else and didn't look at it too hard. Not sure why I have no algae, but all I ever see are filaments and cyanobacteria. I do have some duckweed in the aquarium, but that's different.
