I got 4 a few days ago. They eat small gut-loaded crickets. It is fun to watch them hunt. They see the cricket crawling on the plants that stick out of the water, stalk them, then jump on them. They are quite quick. I jeep them in a half filled 10 gal tank which stays at 80 F durring the day and 75 at nite. They have some rock islands and plants to sit on, but spend most of their time floating.
