Panda cory fry, 5 days old and <1 day old.

The one on the left is 5 days old, the one on the right is about 12 hours old. Ah, they grow up so fast...... The new little guy hatched out sometime early this morning, and is freakishly big. He's almost as long as the older ones! Look at that cute little (big) yolk sac, though.

The egg on the far right (and several others) will hatch in the next day or so, I think. You can really clearly see the developing larva inside, and every once in a while it twitches and wiggles. I got all geeky and made a labeled picture:

It may be easier to see if you click to enlarge. The eyes, tail, and "dorsal saddle" of pigmentation and internal organs are pretty clear. Most of the space inside the egg is taken up by the yolk sac.

Just amazing.

Oh dear. You're being a bad influence. You're making me think about setting up another aquarium. I haven't had one for over 13 years!

Thank you so much for the little tutorial on Panda cory! My daughter and I love watching the little critter's development.
