We ran into the bedroom and she was pointing at the tank, which was almost out of water due to evaporation. Near the bottom of the tank were a few small white objects moving. The white objects were triops! We counted 5 or 6 of them. The video below shows one moving around the tank.
We filled the tank back up with water and dropped a few pellets of food into the water. Now the trick is keeping them alive. I have to admit being just as excited as my 8 year old at discovering live triops! Very cool!
