Tub size for 130g baby

[starmom]

I currently have Jade in a 15 qt sterilite tub. BTW it has been so much easier than the tank. Humidity is great, she eats regularly, and sooo easy to clean. She's about 130g right now....I'm wondering when a bigger tub is needed of if she'll be ok in that size for a while?? Thanks :-)

I have my little 200g girl in a 16qt. I wont switch her out until she's really cramped; maybe about 400g...
