10 Gallon Tank Newbie, red plant leaf black spots

Hi,

Below is my red plants. i dont know the name. it was very red when i got it from the store. now it is barely red. it looks green on one side.

The problem is that the older leafs has black spot and are dying. The plant is continuing to grow new leafs, but older leafs are struggling.










i keep the tank next to window...so plenty of light.
i dont use fertilizer, because i dont know what to use.
the substrate is just sand.
Do i need to fertilize?
And what is the name of this plant?
the tank has over 25 small size fishes, like tetras size.
And has two anubius(have black spots too) and some java moss (doing ok).

Thanks!

You definitely need to fertilise

 

Yes this is a hard plant to grow, you would need a substrate like soil and fertilizers would definitely help. The sun light will also cause a lot of algae issues a light that you can control yourself would be better if possible.
Also those look like goldfish in the tank? 25 is a lot of waste to deal with in such a small tank

no, that is a Gold Balloon Ram.

 

Plants can melt and change color when introduced to a new tank, the older leaves dying is normal too. Some snails and/or shrimp would probably do some good to clean up the algae and dead plant matter, that way the plants you want don't have to compete with algae for nutrients and CO2.
