..what do you think this is? Parasite? Critter?

The more I look at it, the more it seems like I overreacted because of the DOA thing and they're all incredibly tiny bubbles..
 
could they be bubbles which are so tiny that they are affected by brownian motion?

If you don't know what Brownian motion is, look it up at: http://en.wikipedia.org/wiki/Brownian_motion and read the history section, which mentions particle movements in water.

Just thought I'd throw that out there.
 
Thanks for that information. I suspected it could be something like that, but wasn't sure if it was actually possible since I am no man of science. I still think the wind blows because it's the work of a giant dragon perched atop an invisible floating castle fifty kilometers into the sky.

Though if it was tiny bubbles that move on their own accord, I'd imagine not many people have a solution to it?

Stop feeding the fish refried beans from Taco Bell.
 
Here's a thought...

... if they're tiny bubbles shouldn't they be absorbed into the water easily- dispersed into the air.

If you take them out and put them in a container- I wouldn't expect you to still have the bubbles if you left it over night. (unless you had a filter or some other source to create new bubbles) running in that container.
 
Seems like if they were bubbles.. they probably should've all dissolved by now..
 
Maybe those things are amoebocytes? You have a lot of snails in the tank. Here is info on them taken from an apple snail website: http://www.applesnail.net/

When there are many apple snails in a tank, the water tends to become cloudy because apple snails have a large amount of microorganisms in their intestine, which help to digest the food, and which are expelled with the faeces. These micro-organisms (amoebocytes) should not cause any harm to the fish and can even serve as a food source for young fish. Fresh food (lettuce etc.) are more likely to induce this micro-organism based clouding of the water. If the snails are fed with dry fish food, the water will stay cleaner.

I'm not sure if these organisms live in the species of snail you have, but I'd imagine it's probable.
 
That's certainly a very interesting theory Tem, and I do happen to have quite a few Mystery Snails in this tank.

I do happen to have Guppy fry in this tank, but none of them seem to be eating whatever I have.. I wonder how big these amoeboctyes are..
 
Maybe they're LIVING bubbles, somehow capable of maintaining homeostasis (thereby avoiding dissolution)!

As I recall, Spongebob Squarepants blew several bubbles imbued with life!

But seriously, this sounds like a job for a microscope. I'm just itching to know what those li'l guys are! Can anyone suggest a good, cheap microscope?

Lol Dee you sound like me. I'm a biology/pre-vet student and I always have my microscope handy in my dorm room. I've used it several times when I noticed something odd in my tanks, like the time a parasite killed off my 3 week old guppy fry :(.
