Help required, Anubias rotting !
Hi, I'm a new member to the forum and was looking for some advice regarding my Anubias.
I recently bought some Anubias Barteri online and it arrived in beautiful condition with a big hefty root system.
It came in 2 pieces so I didnt need to cut it, I just attached each rhizome to a large piece of bogwood I've had in the tank for about a year.
Within 2 weeks I noticed the roots and base of the leaves begin to turn brown, so I whipped the whole piece of bogwood out of the tank to inspect it further.
I notice that 2 out of 3 specimens of some Anubias Lanceolata I've kept successfully for over a year were also suffering from the same problem.
The roots which turned brown fell apart as sludge as soon as I touched them, leaving just a fibrous inner root.
Several leaves also fell off as soon as I pulled it from the water and I notced the base internodes that attach to the rhizome were brown and soft.
I proceeded to detach the plants from the bogwood to remove any dead parts and to my horror discovered that the complete underside of the rhizomes of each plant were brown and mushy and disintegrated on touch.
Suffice to say I've lost pretty much all of my Anubias apart from one Lanceolata which seems largely unaffected.
When I took the bogwood out I noticed it was very soft to the touch so I began to scrape it with a scalpel.
I found that there was a layer of what I can only assume is rotten wood covering the entire piece and I ended up removing loads of surface, dark brown/black sediment from it.
I've hosed it down and it looks ok, you can see the clean,light coloured, solid wood underneath now as it looked when I bought it.
It seems as if this is the culprit, but can rotten wood really have that affect on plants ? Especially ones as hardy as Anubias ?
I've left it in the bath for now because I'm considering binning it and starting again but it's such a lovely shaped piece of wood that fits perfectly in my tank.
Just for added info my tank is an Aqua One Aquanano 40, all water parameters seem fine, I dose with ferts every other water change, it's been up and running for close to 3 years now.
I'm successfully growing dwarf sag and water lettuce which haven't been affected and are doing well.
My lighting is the new Aqua One 10watt LED
I have 6 Black Phantom Tetras, a glass cat and 3 Otocinclus which are also doing well.
Any help would be great as I'm pretty annoyed at the loss and dont want to buy any more plants until I can narrow this down.
Thanks in advance,
