I have had my two Cherry heads for a month now,(both hatchings) they get there morning soak, sometimes afternoon too. But I learned, if you make sure the water is warm , then soak and wait till it starts to cool, then replace it with warm again, they poop right away. My largest one (Rizzo) gained .2 this week and my smaller one gained.3 this week. Both LOVE the warm water, they both go to eat right after the spa time. Thanks to all the helpers on getting my set ups perfect. I also jornal on what they get for food every day and weight once a week at the same time. Glad they are growing and seem content.
