I have to share!~
A few months back I got a GBTA from smeese. When I got it was pretty small but within a month it had regained its former size of about 4-5"
I added a pair of maroon clowns after that and I've been feeding it twice a week since. It had grown to about 8" or so... and today it split on it's own.
I checked it at around 10am and it was a little deflated, but not much.
A few hours later it was split into two. Now I have one for my nano too!

Mary, I'm hoping yours splits soon too, then perhaps we can trade'm.
