1 Fish, 2 Fish, Dead Fish, Undead Fish

So I'm not much of an animal person, but I have had fish for a few years. They are a unique kind from Asia, White Cloud Minnows. They are somewhat colorful small and difficult to kill. Not that I am trying to kill them on purpose, I just was less successful with other kinds of fish. I believe the words they used were resilient, to temperature changes and pH level changes, etc.  They were just the right kind of fish for me.
  However, since I have moved 3 times in the past 5 years, moving them has become less fun each time. After the last move, I decided that I would not maintain the typical number of minnows to 5-7, I would just let them die, naturally....In their own time. I started with 4, and one died a couple months ago. They strangest thing happened last week though. I had a fish come back to life. Seriously, he was stuck in the filter. I thought I would get him out the next day so I wouldn't smell fish on my hands since I was going to bed.

I tried to take pictures of my tank, but even with the underwater setting it just wasn't working, so I'll try my best to illustrate my point. Here you can see that one fish is stuck in the filter.

This is the next day. Two fish are again swimming in the water....

First I was shocked, doubting that he was ever really stuck in the filter. I quickly reminded myself that he really was stuck in there. Are there any life lessons I can learn from this? I would have put more that to that, except that that fish was on his side in the bottom of the tank that evening. I guess I can say that they are true to the advertisement: Die Hard minnows.
Here is his final resting place (between the rock and the leave plant you should be able to see his red tail attached to his silvery body).

If there were room in the label,  I would change this one to, "stranger than fiction."
