Very Suspicious Anubias Rotting

[Aqua Hero]

So I have had two types of Anubias (Anubias bonsai and Anubias nana Pettit) planted in the exact same spot and in both instances, the rhizome starts to rot and the leaves start to die.

I didn't glue the plant and I didn't bury the rhizome I just placed it on top of some wood. Nothing was covering the rhizome.

I have other anubias in places close to this spot and they are growing fine as usual (and these ones were glued down).

I should not that I do cut the rots of the anubias down before planting as they get in the way.

Does anyone have any ideas why this is happening?

It's probably Anubias rot or melt. There's a few older threads on this somewhere here; one below. It's happened to me too fairly recently and many other members in the past. It's probably infected nursery stock and I don't think there is very much you can do about it, except perhaps try again with new plants. @G H Nelson came to my rescue with new plants and so far they're thriving.

It's probably some sort of systemic microbial disease triggered by a change in environmental conditions. In my case I went on vacation, and although I left my tank in the care of a house sitter I think the outcome is unfortunate but perhaps predictable and only to be expected.

Anubias melt !

Hi, I bought three large Tropica Anubias from Pets at Home just before Christmas in readiness for a new 125L tank which was to replace the 70L tank about a week later. I put the three pots in my existing 70L tank, which already had Anubias growing in it without any trouble for the last year or...

I see. Do you think I should buy my anubias from a different seller then?

I think it must be fairly systemic throughout the industry, and a bit hit and miss. But yes perhaps that would be the best course of action.

Best ditch the compromised Anubias.
