Hi I just got my new baby boys Monday. Love them already! My question is the cage. I was told to keep them in a large aquarium to start. We are syringe feeding them twice and day. I was told they are approximately 7 weeks old. I'm feeding them 4-6ml each twice a day. And was told max 10 ml. When do we start weaning them off the syringe and for how long should they be kept in the aquarium. We got them a large double unit critter nation cage with the additional add on unit for their permanent home. We also got them a large chin spin wheel too. Just curious how old they need to be before we move them tontheir big cage.
