Thanks for the info, guys!
Byron, that 33g looks spectacular! Why, why, why did you ever break it down??
The book you recommended came last week (Peter Hiscock's Encyclopedia of Aquarium Plants) and it's a great book. The chapter dealing with propagation on rhizomes says each division should have at least one good shoot. I don't see any shoots on my rhizome. I'm going to go ahead and cut it in half and we'll see what happens.
I just did a huge water change and used Hiscock's methods on dividing and pruning my plants. Already it looks much better and hopefully I'll see some great growth in the coming weeks. I changed out my fert program as we discussed last week and already there's been much improvement. I'm excited! I don't think I'll ever have to buy another plant again.
Thanks for all the help & great advice, much appreciated.
PS. What species of anubias is that in the 33gl?
