[Can anyone tell me what these little creatures are?]

It is definitely is something larval, and really does look like a tiny hellgrammite, but that was the best photo I could get with my DLSR camera.... so that's probably the best that I can do. The little guys were probably only 2-3 mm long.  One odd thing that I noticed was that their mouths were hovering towards the surface like they were trying to breathe air. I had to go away for a few days so i just crushed them in case they started attacking my shrimp. If i notice any more I will snag it and move it into a tiny jar, feed it, and watch it grow since i would love to see it in the adolescent/mature stages... I just don't want to see that happen in my aquarium XD. 

And to Mr. KrazyJohn, since I am away i cant get a photo of it but its lost all of its "banana" bits and now just shoots off lily pads every few days.  They've gotten to be about 5in diameter so I trim them back once every few weeks. But it did look like the banana plant that was advertised for ~5-6 months.

I just noticed them today sitting on top of the one leaf of my banana plant, the multi-legged ones not the snails. Also the dirt is because I am a fool and listened to someone that recommended that I use a more natural substrate for the gravel.
