Yellow anubias overnight

I got an anubias for my betta tank about a week ago, I'm not sure what type but it is flowering. It has been looking healthy until this morning when I noticed its leaves have turned yellow. This happened overnight, it was fine yesterday. There's only one betta in the tank, could it be a nutrient deficiency? I use apI leaf zone once a week.

 

 

I've tried using charts like this with varying success.




I think that one is from Arizona.edu Google plant leaf nutrient color chart. I'd say yours looks like nitrogen deficiency, but your interpretation is as good as mine.

 

Thanks yeah I think it looks like nitrogen too. I've put in a root tab but maybe a liquid fertiliser with nitrogen would do better for anubias as the roots aren't buried. Any fertiliser recommendations?

 

I was told to use flourish, the iInternet swears by it. I've tried their macro nutrients (they sell nitrogen, phosphorus and potassium individually) and their comprehensive supplement which is all the micro nutrients. I have yet to have great success with plants, because while I tried every supplement under the sun, I never upgraded my lighting. I just started a new tank, and lighting is on the to do list. So even though I never had enormous success, I really don't think it was the flourishes' fault.

 

You can plant Anubias as long as the rhizome isn't covered. IMO it does best tied down though.

 

Mines on driftwood, hopefully the root tab does something still. There's another anubias in the tank that's doing great, it's not yellow at all. so weird. Will order some flourish liquid. Cheers guys.

 

Unsure what other plants you have in the tank but if you have any form of jungle val I've heard flourish is very bad for it. If not, I've heard it's great!

 

In that case it's likely adjusting to aquatic life? Many plants sold go through this phase because they were grown out of water.

Vallisineria can melt when using Flourish EXCEL, which is NOT Flourish (comprehensive). Vals can be acclimated to EXCEL, starting with small doses and ramping up over time to the normal dose.

New plants often melt when introduced to a new tank. As long as there is new growth coming out of it, then the plant will usually recover well. Root tabs will not help anubias plants as they feed from the water column. You'll need to add ferts the the water. If the root tab is buried, it will leak a little bit into the water column, but probably won't be enough to help.

 

I have Val's in one of my tanks. I dose the equivalent of 22mL of excel daily. The issue with them is they don't like sudden changes. Don't miss dosing days often, don't dramatically increase/decrease dosage and it will be fine.

 

The plant was in water at the store but they had a lot of fish in with it, at my place it's only got one betta so I think it might be suffering from having less nutrients. Have ordered liquid ferts. Thanks for the opinions

 

That's sound plausible to me. If you put them in a couple of weeks ago, perhaps they've been using the nutrients available these last couple of weeks from your Betta, but now they've run that source out. So you maybe had a a few ppm nitrates available, and now they are used up. I'd be curious as to what your nitrates levels are now. Any chance of testing? I'm guessing near zero, which if you haven't done a recent water change should presumably not be the case, except that the plants have use it all up.
