You can try Hikari Mulberific. Most tortoises love them from the first bite.Thank you!
I have some pellets but he has never shown a interest in them, Ill try maybe putting them onto his greens after soaking them.
Should I keep the night time temperature raised for now please or would you drop it now hes eating?
Yes, keep nighttime temperatures high at least for a month. Then you can lower them to 26-28C if his appetite is still good. Also, as he is eating now you can cut down carrot/Reptoboost soaks and settle down on daily soaks in clean water eventually.
