I'm feeding at least twice a day, but often three times: before I go to work, when I get home, right before the lights go out. I actually changed the schedule of the lights (turning them off mid-day) to accommodate that third feed.
Let us know when they need a home! I think I can find a place for a 20 L or a 29 around here somewhere for a pair of them!
I'll have to look into shipping supplies. It's not something I've ever done before. I was honestly planning on just trading them with my LFS, but if people want to pay for shipping, I can certainly send some out (summer shipping might be a problem though).
