This is a dymax IQ3 pico. It's approximately 2 gallons but I think it's really less. It's been up and running for a little more then 6 months. I'm actually waiting for a par30 led bulb from rapidled and once that comes I will be doing a few changes that should finish off the tank, but even now it's pretty full.
I've never seen the sexy shrimp so active. They're always dancing around but never this fast. It may because they have started mating.
