I glanced in my 10 gallon a minute ago and... Jade's side is SWARMING with tiny little worms. My granpa's hundreds of baby guppies would be in heaven. Except it's pretty hard to transport these worms from this tank to their bucket.
Crawling all over the glass... flying around in every which way in the tank... shoot, if only Jade would build a freakin bubble nest and keep up with it for a female, I'd totally breed in this tank.
I'll post pictures, though... if I can capture those small little things.
Let me know if they really are infusoria. (Jade's side has quite a lot of plants... or at least thick ones. :P )
