Well I phoned the vets this week with the last weights and the vet we see was off but they were going to let him know this coming Monday so fingers crossed.
Also the smaller one-Bee started croaking last night

The larger one Ninja has always croaked, then last night he got a little tiny response. Bee has been very shy all week then when I came in from work last night he was out and I thought it was it was Ninja as he was so big, but then I saw Ninja (he is very much set on staying brown whereas Bee is mostly green) on another leaf next to him.
They both seem to go shy (hardly come out) and not eat so much when they are shedding, they pop out for a soak in the water bowl but seem to have no appetite for a few days, then the next time you see them they look bigger.
