In those pix, they're in 20g, 120g, and a 90g. The majority of them have since moved from the 90g to a 400g. Within the next few weeks, they will be split between the 400g and a 340g.
A 210g should be able to house a few for atleast two years with the right filtration and WC schedule.
Here's an update.
My cousin and I moved the azuls, kelberi, and ocells to a 400g temporarily. Half will stay, the other half are going to another 340g growout. We lost one when he jumped through a small opening above an overflow
Here are the pix:
First, dead azul, wild columbian ocells, and my kelberis
