I split this and now have one culture that is not aerated and one that is.

Took some more pics today that allowed me to get some measurements in these guys. I like the size and hope to try them as a food for rusty goby larvae once the cultures are going strong.

This is very nerdy, but I really like looking at these guys under the microscope
 
I have been toying with different culture conditions and right now I have three cultures going.  One of them, I am trying to see if feeding RG complete helps increase numbers, but if I can get it to grow in higher densities by just increasing the amount of light, then I would rather skip the extra feeding.

I am finally getting this to grow is good numbers.






I may finally have enough to use to test as a possible food for Priolepis larvae.

Keep up the good work.  I've always wondered why more people didn't culture dinos.

It was a gift from a university lab. I can pass some along to you if you want
