Hi pseud,
If you damage the rhisome, in app. 2 weeks time you will see that it is recovered and will also produce a forked rhisome exactly from that part. For example you can have more than 10 anubias from a 10 inches healty anubias.
The two sentences are not related to each other, its my error it seems so.
At first sentence what I meant was something that I discovered accidentaly. I was cutting out an old yellowish leaf with a blade as close as possible to the rhisome, because if some part of the stem of the leaf stays with the rhisome it will decompose quickly with an ugly sight. But during the cutting blade slipped some and made a crack on the rhisome about 1cm in length and app 3-4mm deep. I got mad at myself for this accident but there was nothing to do and I left it in that way. I watched carefully everyday what my clumsiness will result but in a week time I saw that the crack is getting brownish but smaller everyday. In two weeks the brownish spot was reduced to the size of a pinhole and I noticed that something green is coming out of it which at first I tought it was a leaf but later it grow and became another rhisome with new leaves on it. At first I tought it was a coincidence and chance. Then I suggested to give a second try. This time I made it on a rhisome which I already considered to cut as it was growing out of the bark it is attached. I made an exactly same sized crack on the rhisome and guess what. Same thing happened and a new rhisome branched from that cut resulting a T shaped rhisome. I liked that very much and considered it as a good way to give any shape and direction I like to the rhisome.
And second sentence was regarding to my regular rhisome splitting practice. As long as the rhisome is healthy, you can cut it from any place you like even as small as it just had 2 leaves and some roots on it. So as an example I said that from a ten inches anubias you can get at least 10 cuttings.
So I can tell that anubias could be the perfect plant only if it didn't grow so slow and easily infected with GSA. It can grow at any condition, it is very hard to damage it and nearly impossible to kill. Flowers nicely.
