I would like to start a tisbe culture, but I'm having trouble finding a good source... the stores with Algagen bottles around here seem to have empty-looking bottles and I don't really want to pay $30 if I can't see anything moving in it!!
I found this, but I wanted to confirm they are really tisbe... he's got a few pics, but I don't know if any of them are close enough to positively identify. I question it because they appear to be kind of large to me...
What do you think?
Thanks
