Help. I'm having an anubias nana petite that seems to be dying. It is in a 23cm tank and the leaves are turning brown or black, starting with the older leaves. Is this a sign of nutrient deficiency?
In this case could there be problems with my light - e.g. too dim?
Please assist as I don't want to be the first guy in AQ to kill an anubias nana.

How much light do you have exactly? And other tank parameters? Fert?
I have the same plants in a 30 cm noCo2/no fert/no filter/no water change tank with moss/ferns and a 15W PL clip on light. And they grow slow but nicely.
But if it does die, maybe we could schedule an interview about this historic event? :P *runs and hide*
Temperature?
More details
23cm tank
it uses a 7w light, you know the u shaped on. brand is ocean free. (not that it might help)
there is hc and hairgrass in the tank as well. hc and hairgrass don't seem to be doing well too, with partially yellow or discoloured leaves.
the tank houses a betta, the only fauna in the fish tank.
the tank was left unattended for the whole of december, with only water top-ups. prior to that there was no fish at all in the tank, only little copepods.
i introduced the betta on 2nd jan.
fertilization is a drop or two of ferka's aquatilizer, and seachem excel (the organic carbon).
photos coming soon...

Think 7W is a mite too little... try switching to a 11 or 12 W PL....
I'm afraid the dubious honor of 'Nana Killer' has been taken. I had a 'nana gold' turn into mush for no apparent reason while the rest of the plants were flourishing.
Only other time I had problems with Anubias was when I added them to a tank with 29degC water, That's when the leaves started turning yellow.

Update -
I released some cheap shrimps into the tank - as an experiment, as the betta is a messy eater - the shrimps hopefully would clear up the food that falls to the ground.
Lo and behold, the shrimp immediately went into my plants, the nana with blackened leaves, and began picking at the leaves! And below the layer of black....were nana leaves of normal colour!
So it means that there was a layer of algae or scum or organic material that formed on the leaves of the nana...
Next thing - I hope the betta does not eat my shrimp. Speaking of which, I'm going to try to put more stones to let my shrimp hide when I reach home tonight...
If you have enough flora coverage, the shrimps should be able to hide themselves pretty well from predators.
Cheers,

I have dwarf cichlids in my tanks! Do you?
It's not enough...because there is only HC and hairgrass in the tank...
For me, my common betta took obvious try-to-eat bites at my cherry shrimps. I left him in that tank because the tank was full of anubias nana and they could hide.
They hardly showed themselves during the time the betta was around and I thought they were all dead. Once I took him out, i spotted 3 shrimps the next day.
