Hi,
There was a sticker on the original tank we bought him i and it stated 10th Jan 2022 (guessing he's about 11 months) so I can only go by this. Since we've bought him, we have fed him every 7 - 10 days, with a rat at approx 25-30gr. Once he went for about 1.5 weeks without food but other than this we've fed him all the time. Last measure he was 90cm and weighed 65gr. We only fed him yesterday so I am leaving him to digest before I disturb him, shall re-weigh and measure him on Saturday.
