Why Is Plant Turning Yellow?

I bought this a few days ago and it looked so good! What happened? I swear it changed colors overnight.

I dose The Seachem line according to directions. (Flourish, Advance, Trace, Potassium) I have Iron coming today.

 

What kind of substrate are you using? It looks like a root feeding plant, so if you don't have special substrate you need to put root tabs in the substrate

 

Is that a crypt? Maybe it’s melting off the emersed growth and just transitioning.

 

It was sold as an anubias, so I have it attached to a rock.

You really don’t need those fertilizers for anubias, imo. Any specific species? The leaves and stems do appear emersed, so I’d expect a lot of melt off, and new underwater growth to emerge.

Really??? I wasn't thinking anubias when I saw that pic.....
Does it have a regular root system? or does it have a Rhizome?

 

She bought them as fully aquatic anf has had them for several weeks. It's only been since moving to my tank that it looks horrible.

I have a fully planted low-tech 20 gallon with crypts, java moss and java fern.

Trying to dodge window glare for a full pic! It has a rhyzome.

 

I am not 100% convinced that is a rhizome.
I'd like to hear some other opinions.....

 

Storm is rolling in, less glare. From two angles.

 

Yeah, it doesn’t look like a rhizome to me either. My original assumtion is that it looks like a species of crypt in its emersed form. The leaves do appear anubias-like, but the stems definitely do not.

Edit: After looking at the new, clearer photos, it is defintely not a rhizome plant.

Gosh, this is tough, I sort of see what looks like a rhizome in there, but if it is...it looks like a dying or broken rhizome, which could explain why the leaves aren't doing well....

If it is NOT a rhizome, then the plant is not doing well because the roots are not planted.

I agree that it might be a plant that was grown emersed. And so it has some transitioning to do. Emersed anubias has been hit or miss for me. I had a couple where the rhizome rotted and the plant died. I had another where all the big leaves melted off and the only new growth were itty bitty leaves. Then I have had other emersed anubias thrive in my tanks. I have never had any issues with anubias that was grown submerged.

I HATE getting plants that were grown emersed. But sadly that is what so many of them are!!

 

It has to be a crypt, although none of the ones I own look like that. It has a crown? and a small runner on the bottom.

 

The more I stare at it, the more I see a broken and dying rhizome.

 

I see crypt. The 'rhisome' part looks almost identical to some of my older crypts that's undergone a few tank moves....

 

Any idea what could be causing the yellowing from the inside out?

 

To me, it looks like dieback from emmersed growth.

 

I think so too. I know you said someone had it for several weeks, but maybe that’s how long it took for the leaves to start dying. I know some non-aquatic plants can take a long time to start melting, which is what tricks people into thinking they’re fully aquatic. I even see a lot of true aquatic plants in their emersed form being sold fully submerged and haven’t even had the filter wool and basket removed from the roots.

 

I double checked when I was at the store today - they were submersed grown, she won't buy them otherwise, and it is an anubias. It has to be something in my tank. The ones left at the store are all beautiful.

 

Ouch. That's the saddest anubias Ive seen!

You may of mentioned it, but what did you do to attach it to the rock? If it was superglue, you may of gone a bit overboard with it - which plants don't like - and may result in what you're seeing now?

 

The reason I don’t think it’s an anubias is because I haven’t seen stems like that before. Granted, I only have two species, but the stems are stiffer, more branch-like, then the stems I’m seeing here.

 

Googling the species showd plants that look just like this one, albeit healthy.

JJ, I did use superglue, just a bit on the very center to tack it in place. I just did a ton (60+ pieces) of java fern and moss in three tanks and never had an issue. I use sparingly!

You’re right. I checked out some photos through Google, and some species do look like yours. Perhaps SeattleRoy may be of help.

 

I knew it was anubias!!
But like I said before....the rhizome doesn't look very good. It seems broken or something....

 

The only thing I can think that's causing this, is anubias rot. Basically the rhizome (and stems) go brown and mushy, they eventually just rot away. Dunno if its bacterial or parasitic, but everyone recommends cutting off the mush/effected parts and allowing it to grow back (with crossed fingers).

 

Okay, I'll cut off the dying leaves and see if there is anything bad on it in the next couple of days. (Flea treatment day for the cats, so I stay out of the tanks for a while after since I end up wearing the stuff.)

I didn't feel anything soft or see any damage to the rhysome or roots. It looked really good when I put it in there.

 

I tied a piece of anubia nana to a piece of wood once. I think having the rhizome in contact with the wood killed it as it deteriorated where it was touching. I was unable to save it but I wonder if you super glued the rhizome instead of the roots to the stone, if that could be part of the cause.
