Ok so last night I was rearranging some plants that my fish uprooted when I noticed a fish in the tube of my undergravel filter

(which I have now decided that they are horrible and just hide "crud" and I would never put another one in any tank I ever own.) I got upset thinking that one of my fish somehow got stuck in there, I did a head count and then I noticed that it wasn't one of my fish that I currently have.

It had to have been a fry that grew up under the filter and gravel. I unhooked the tube and let him out (he is gorgeous by the way) and decided that I just needed to get rid of the filters. I pulled both of them up and found ANOTHER guppy!!!! She is pretty also just doesn't have the vivid colors the other one has. Both fish are pretty large (the male is the size you would buy from the lfs and the female is actually a bit larger than what you would buy). The "crud" was pretty bad (the undergravel filters have been in there for about 1 1/2 yrs.) so I had to do a 60% water change and I am going to do another one tomorrow night. Everyone seems to be doing fine, but I was absolutly astonished that two fish were able to grow up in such hard conditions b/c there isn't a lot of light and the crud that was in there was pretty bad. My husband thought I was crazy and seeing things when I first told him, but when he saw it he started cracking up! The entire time I was doing the water change I would just periodically start laughing. Has anyone ever heard of anything similar?
