My wife put 30 of the scuds in each tank. One tank is in a greenhouse without heat that is attached to our walkout basement on the south side of the house and stays above freezing. The other tank is in the basement and has a bubble filter running very slowly. It also has a light on a timer, and has gravel on some of the bottom. A flat piece of slate will be added today, held up on some stones to create more cover and dark spots. There was already algae growing in the tanks as they have been set up for a while. They also both have established plants that were collected from one of our shallow ponds. We have started by feeding shrimp pellets which they immediately attacked. They will also periodically get "green water" from a tropical tank that is overpopulated with swordtails. Not enough time has gone by to know if these will survive and breed. Right now, they are crammed under the filter for cover.
