Fish Tank

Strange things are happening in our fish tank. First off all but one of our aquatic friends have kicked the bucket. We had one fish left, Blacky. Derek won three gift certificates from the school fair for a free fish from a really nice pet store. That is when we got the 3 fish. We decided to get some snails to help clean the tank.

So I thought maybe Blacky was getting depressed being in the tank all alone so I decided to get some more fish. Well and a snail because the tank needs cleaning! We decided to go to a cheap place in hopes of getting fish that live more then a WEEK. We got 2 more fish but they were out of snails. The gal at the store said we could not have plady's (sucky fish) because we don't heat our tank but she said this other type were hardier and it would probably be okay. Plus if it dies we can take it back for a refund. So we get one.
Okay so now everything is normal, I thought.

Today i noticed a strange tiny little flibbity jibbit in the tank. What could it be?! AND a teeny tiny swirly snail. Not the kind we had before but the kind that look like little gnome hats. I wonder what will turn up in the tank tomorrow!!!!!
