Hi Meg, after the water reaches temps above 55 on a consistant basis. Do not feed them on the first 55 water temp reading, wait until it is consistantly 55

Meg, when the water warms you can consider feeding veggies like broccoli flowerettes and shredding zuccinni as well as fruits. They love earthworms and slugs as well. My guys get these treats in colder water and then mixed with pellets as the water warms up.
