Why Are My Anubias Suddenly Dying

[clutterydrawer]

Hiya

I've got two anubias nana and an anubias nana "barteri", attached to wood which have been perfectly healthy for getting on for a year. Suddenly they're getting holes in the leaves where the green-ness has vanished to leave lacy patches, and some stems are turning yellow followed by the leaf falling off.

I've not changed anyhting recently, so does anyone know what could be causing this?

Thanks.

I think you need to offer them some ferts both via the roots (substrate) and waterborne. They are definately
difficient in one or more vital neutrients. Ask gf225 for more insight into plant fertilisation as he had an Anubias which actually flowered in his aquarium.

I was told a while ago that the roots shouldn't be buried. I never bury the rhizome. Maybe thats why mine don't do very well in the long run.

Its odd allright..........i dont really know, has your water supply changed at all recently? the plants were obviously getting all they needed from the water column up to now, if Anubias have enough light and fertilisation through the water column they should do fine they dont have any special requirements other than that, the fertilisation will come in the form of nitrates phosphates and trace elements all of which will either come from your tapwater or your fish waste or from the fish food, try dosing a general purpose fertiliser like Seachem flourish or Kent botanic grow to the dosage recommended on the bottle and see if that helps.

I am having a very similar problem with a large anubius in my tank. It was going along very nicely for over a year and then all of a sudden its health took a turn. This seemed to coincide with me moving it to another section of the tank. In both locations I buried the roots but made sure the rhizone was not buried. Over the course of a couple of months leaves developed holes in them then eventually fell off. The new leaf growth became gradually smaller and less frequent. I moved it back to its original location and attached the rhizome to piece of bog wood hoping that this would save it. It hasn't helped and now most of the rhizome has rotted away leaving a couple of short stumpy roots and two very small sickly looking leaves. Oddly I also have some anubius nana in the tank which seems to be doing fine. Even flowers occasionally. Originally I thought it may have been a nutrient deficiency but the relative good health of the anubius nana has me wondering whether it could have been beset by some disease.

That's interesting cos now I think of it I did move the two little ones from one tank to another a while back...but I didn't see it as relevant cos the big one has always been in that tank and that was showing the same symptoms...hmm

I'll try dosing some liquid fertiliser, I cant give ferts via the substrate though cos the plants are attached to wood.

One of my Anubias suffered exactly the same fate.....I was away for 2 days and came back to find my previously healthy plant ripped apart...leaves turned to lace and floating.
I put it down to my fish because my other anubiasasas!! are fine. I think my syno catfish might have had a go at it in the abscence of daily feeding?
