Hi Matt, thanks for the reply.
Yep he has a fluro basking lamp, it's on a timer. We have been feeding every other day now - seems to be working, he eats every thing put in front of him. I have been told of the ox heart so I will try him on that
we've been measuring his shell once a month usually grows about 1.5cm each month and puts on about 100grams a month. He gets to go walkies outside every now & then - he's not too keen being out of the water for too long though.
