Excellent images.

A very dramatic shot. More interesting to me than the others.

I see the stinger, but the parts hanging down around the umbrella look like Hydra. And what are the red dots? Light organs?

Well, good luck, but just keep in mind the movie with Steve McQueen, "The Blob". You don't want to wake up one night with that in the room. LOL

I would say your tank is really healthy if you had a bloom of jellies in it.

And excellent pictures. Did you find them just by chance, or was the bloom big enough to "see"?

He is very weird. How did you ever identify this as a rotifer?

HAHA, excellent perspective. Like floating through the clouds in a green blimp.

Reminds me of Alien.

Beautiful as always, but in #3, what is that at the bottom of the diatom? A slime trail?

It looks like an alien landscape bombarded from space. LOL The colors are so pure though.

Very nice. #2 and 3 especially. Do you use a dark field condenser for this effect?

HAHA, the amoeba held on with a string, even after the alga got away. You could see it jerking with the alga at the end. And a very interesting pattern on the algae.

beautiful colors. Could it have absorbed moisture?

Empty eggs from some bug. You can still see them in their original matrix, like a mosquito raft. I have seen egg rafts before, but did not have a scope to look at them. Looks like the bottom right one may have a larvae still in it.

From what you wrote, I am quite sure you will need either a "projector" lens, which is a lens that goes into the trinocular tube if you had one, and so is between the light path from the slide and your camera sensor. It looks like an ocular and an ocular will work in a pinch. But while Nikon for exa...
