Unhappy Annubias nana leaves becoming brown and melting

Hi, I am very new to aquatic plants and planted fish tanks. I started a nano tank 3 weeks ago with 2 annubias nana plants and added a Betta fish with 2 Nerite snails just a week ago. The plants were turning slightly brown after the first week or so. But within the past past 1 week, I noticed that the leaves are totally brown, they are falling off easily and melting with only the frames/veins left (Photos attached). I wonder what could be the cause. Any suggestion is greatly appreciated. Thanks in advance.

Do you have any photos of the plant before it melted back? It's really hard to tell what is could have been at this point..

Hi, yes. I took these pictures, when I added the fish 7 days ago. They are not very prominently visible though, but you should get an idea how they looked a week ago. The colour is probably a bit enhanced.

Assuming you purchased these at the LFS, the anubias were probably emersed grown, not submersed grown. Add these to a new tank that may have not been completely cycled and that's probably the cause of the issues. I started up a new tank about a year ago with 6 anubias, about 33% did the same thing, just melted and died. If the rhizome remains green, keep it and the leaves will grow back. If the entire rhizome melts or turns brown, toss it, it's dead.

Thanks. I bought the plants from a local pet shop. There the plants were fully submersed in water. I did not (and probably still don't) have much idea about submersed or emersed growth. I will check if the rhizome is okay or not.

The LFS will submersed the plants in a display tank. But most likely they were emeresed grown at the aquatic nursery and only arrived at the LFS a few days earlier. See here and here for sites that explain the differences.

One of the better places to purchase submersed grown plants are from The Planted Tank members here on the For Sale/Trade Forum. Highly recommended, I much prefer to purchase here as opposed to the LFS.

Are you using any fertilizer. If not the plants are probably starving for nutrients like N, P, K. Ca, Mg, S, Cl ( the macro nutrients) or Fe, Mn, B, Zn, Cu, Mo,Ni (the micro nutrients). A fertilizer like Nilocg.com Thrive would probably work

Hi, I live in Germany actually. I will try to find a seller that sells submerged grown plant here or put up a post to know if someone in the forum sells in Germany. Thanks for the info.
