Mine was less than 1/4" when I got it, browned out and took months to come back. 1/4" frag was $50 + 45 shipping. Very expensive but it was free because I won the $100 DIY contest last year. I would have never bought it for that and would have been bugging you for a piece (as it seems no one has it) but I got lucky. Beautiful Colony you have there, my stub is about 1/2 " around now, 1" tall and a little 1/4" nub growing on the base which is about 1 1/2"...,,,after 9mths or so lol. Slow grower w hen its that size.
