Yeah I have noticed that about the Aussies too!...
I have also been monitoring the ones I had culturing on Flat Surfaces and on Bumpy surfaces.. And you guys are right, they do grow quicker on the flat surfaces!
cool...
Its also a good thing they grow quicker than the Indo's too because well.. NUMBER ONE they are nicer! and more colorful!
Second, that means, if Austrailia ever shuts down collection, we will still have our Acans here to be able to culture, and culture much quicker at that.. which will in time decrease wild collection if someone can start culturing them now.
