I just explained the whole infusoria/bbs thing to him (after my wild goose chase to pet stores today) and he laughed.

If you want pictures, here is the first of what will be many...I hope:



I thought they were all dead today because apparently, when they hatch, they drop to the bottom and lay still. Then they come back up and stick to the sides or whatever they cling to. In between those two events I was sure I killed them all. There are a handful sticking to the sides now. I'll try to get more pictures tomorrow. They're still soooo tiny.
