Wish mine bubbled like that [emoji24]
I can't say for certain but they seem to do that for me when they are happy with their lighting. At least one factor that I've seen. When I had my previous lighting they did that as well, then I switched to another type of lighting and they lost all bubbles, and now with my new lighting they are filled out again very well. The iron dosing seems to have helped their coloration.
