THE AMAZING ZEBRAFISH
spazoid
You're familiar with the little zebra danio, aren't you? Those spazzy, hyperactive pet store fish that are probably the cheapest things in the joint. Well, that humble little fish could hold the key to regenerative heart growth in humans.

I can't track down the source right now (actually, I'm just too lazy to hunt now), but this common little fishhead has been a prime experimental subject in all that DNA/genome research that's been in the news lately. I guess it's got just the right genetic code.

I kept a small school of danios for a long time. Loved them, always scooting around the tank at full speed. Very entertaining. I gave them to my friend Tom. I kind of miss the little buggers.
