Our tank's biology up close

Couple perameciums chilling with some diatoms

Not exactly sure what this was. Possibly the same thing I caught up with later that I think may be a rotifer as well. ? This one though is slightly different. Maybe just a basic ciliate?
 
Interesteing shape at 3:31. Maybe something to do with what I found at the end. Maybe not.

Otherwise I caught back up with that mystery things in the last post closer up. It's very interesting looking. Almost crustacean like when looking at it from the side when it flips around.

At 3:38

Rotifer? Walking Ciliate? Some type of crustacean?

Not exactly sure what this is from and it seems like a molt from something? but I like the patterns and colors.

 
So, here I am at 100x and I end up viewing the business end of a pod again... lol

This time I was trying to focus more on it eating which was pretty cool


 
Another thing I had not seen before. Well, I've seen these before but not with flagella like things sticking out and moving. Possibly just seeing it for the first time with better optics. Now I'm curious what it is.

First few seconds is the most exciting. After that it just sat there doing nothing like I'm used to seeing.

Found this critter twice and I think it's a type of rotifer. It can move very very fast it seems. First video is the first one I found and didn't jump around like the second one I found.

1st encounter


2nd Maybe the same as the first one or a different one. Very hard to keep focused on and follow

Zoomed out and it would still just kind of twitch and bam it's in a new spot.
 
Then started playing around with the darkfield again and playing with the gain in the software. Made lots of things over exposed but brought out other things well.


This was cool. Not exactly sure but it seemed like the cyano was trailing off new strains behind it.


Could really see some of the bacteria and smaller organisms moving around. Like exploring through space.
 
While I was playing around with the darkfield I ran accross the weird overexposed object except it had feelers, for a lack of a better word, stretching out all around it. I went back to darkfield again toward the end of this video. I didn't have it recording when I first ran into in darkfield.






 
Man getting all these uploaded has been challenging. First a unplanned reboot killed my uploads, then ran out of battery thinking laptop was plugged in killed the uploads again, then a forced windows update and reboot killed the uploads again, and then was on spotty wifi and kept stalling the uploads...

2 of the samples have been uploaded finally. Still getting the rest of what I captured uploaded...and it's the mystery black mat.


So, here's what I've gotten uploaded so far. Samples from member karimwassef.

Each sample I sliced off a chunk and sucked up some with my pipette as usually.

Have wide cover slips just for this.

Looks like some kind of brown algae with the green algae.

This is what I believe to be a type of cyano but haven't seen it in my system. A lot more of it in the other samples.

Sometimes the pictures look out of focus but if you look around you'll see what I was focusing on. :)
In this case it was the spirochete bacteria. They are pretty cool.

Here's the thick mass taken from the bag. Lots of cyano mixed with algae

Great work as always, Jason!

I have to ask. What magnifications do you find most useful for algae and bacteria identification?
 
Video on flikr for now and will get up to youtube later. Click on the picture or link to see the video.

There is one more video but looks like it failed to upload. I'll work on that once the black mat pictures and videos are up.
