Ah, yes! It is closer to 20. I just obsessively counted them. They're all just so fast that it is hard's hard to keep track! Thanks again DUKENBEARS.
Also, I don't know if it was the moss, or maybe the red tiger lotus/moneywort I got from other members, but I suddenly have some mystery fry swimming in my tank. They're too small for the microworms I have, but luckily I've had a green water container set up since last year. This should be an interesting adventure. Who doesn't love a good mystery fry?!
