More (weird) pet news

Ok, so we have fish.  We have always had fish.  We always have a few going.  One dies, we get another- it's not a big deal, and it supports our instant-gratification & "embrace change" thing we've got going.  So... since before we left for Thailand, we only had one fish.  No biggie, we enjoy it- and while I'm not sure the snails provide it much companionship, I wasn't it a big hurry to fill the tank back up.
Yesterday, Boss Jr says, "Hey Mom, we have 2 fish now."  And sure as shit, there was a tiny clone of the big one in there, zipping around!!  I'm so confused.  Really, how does that happen?

Blurry.  But it's SO tiny!

And by the end of the day, there were 2 babies.  The second one is just as freakish as the first one.  The big fish keeps huddling under the bubble machine, like it's a nest.  I'm not sure that I'll ever get the answer of how/why this is happening, but it'll be interesting to see how many wee ones we end up with.
