I tried this last year and had no good news. The babies were kept in this tub with an incandescent bulb.
They were fed Hills by tube once every 2 weeks. In the attempt they had a constant amount of food in the tub.
For 1 week pinkies, then frogs then lizards. Same story every month for 4 months till they decided to pass on the same week.
I had a problem forcing because they have a very strong mouth and I would pulp the pink before it went in or they would just throw it out as soon as possible.
Holding them on their back does help to calm them down when forcing.
This the is previous years setup. All these guys are CB from the Western Cape.
