Diatom? Algae? Harmful?

[SaltwaterGuruNeeded]

I believe this to be Amphiprora alata. I can't seem to find if this is harmful to my fish or not but I've found them on my fish and I'm having trouble identifying a disease on my fish. I have alot of these. Could anyone please educate me on this, if it's harmful and such? Is it a diatom, microalgae, disease, parasite? Btw it moves.

Whatever it is is going through mitosis. Might make a hard id harder as its guts are being stretched out. That does look like one though.

Yeah I had it in a slide for a while, couple hrs. I can get another picture of a live one...just need a minute. And actually I don't think it's going through mitosis because they all look like that.

I edited after I said. It does look more pinched at the center giving it that look of going through the process. Plus the guts don't look right. If it is a toxic diatom that would not of killed a fish in low numbers. It would take a reasonable bloom of them.

Best I can do wet, very hard to see in water.

It does look like that dino. Did you look into video. Check and see if your lenses can do oil emersions. Can get really good pictures that way.

It can.

Put a small drop of oil on top of slides dip lense into it.! Could make a much better viewing exp.

Oh, ok I can go up to 1,000x and then I also have 2 20x eyepieces so I can get 2,000x

That was taken at 400x with phone zoom.

 

[SaltwaterGuruNeeded]

Ok 1,000x oil with 3x phone zoom.

agreed

harmless diatom

agreed

harmless diatom

Thanks

Confirming amphidium. Dinoflagellates are protists organisms -those that do not fit within the three natural kingdoms: animalia, plantae or fungus- with ability to move with rotating movements. All dinoflagellates have the common feature of having two flagella located at right angles allowing them to perform such rotational movement which makes them easily recognizable (although some species such as the genus symbiodinium they are virtually immobile).
There are about 2.400 species which have a highly variable size ranging from 20 and 300 µm in the most common ones and up to 2 mm in the case of species such as noctiluca. In the marine aquarium species are usual smaller as symbiodinium and Amphidinium, While some like ostreopsis are large and can be seen without a microscope (with good lighting and visual acuity).
The problem arises when conditions in the aquarium break the biological balance and some dinoflagellate species spread uncontrollably, smothering the rest of the aquarium inhabitants. If the dinoflagellate species in question has the ability to produce toxins (usual in ostreopsis, gambierdiscus and prorocentrum to name a few)
The problem often arises when we try to bring cleanliness it to the limit, in order to improve its appearance and color of corals.
They tend to occur suddenly when the aquarium water reaches an extraordinary cleanliness, in which most microorganisms perishes for lack of food. With no other organisms that can stop them, this type of dinoflagellate can multiply so fast that when we realize it's late and we will find an aquarium full of brown and ochre slime suffocating fish and invertebrates. These dinoflagellates possess chloroplasts enabling them to synthesize their own food even under a minimal amount of light. Some species can form cysts called pellicles which allow them to remain in the aquarium for months although we have completely sterilized or kept in complete darkness. Once the light or the right conditions come back, they will reappear and thus problems.
Most of these dinoflagellates have a very curious behavior, typical of pathogens and parasites. With the presence of light they secrete mucus which adhere to any surface, including algae, coral and fish. They spend hours synthesizing food and extending vertically in search of the light source (if we turn off the pumps in the aquarium we can see brown filaments grow towards the surface). When the light source disappears and can no longer synthesize food, it begins to diminish to none.

Thanks, very interesting. Lots of info!
