Decor In Fish Tank

[JT-SCFC-1912]

I'm looking for some advice, recently got a large fish tank, and looking to keep the decor quite simple

Can anybody recommend certain rocks/plants which would look great and beneficial to the community

Thanks

What do you mean by large?

What kind of lighting/stocking will you have and will you be using any fertilisers or Co2?

I have 2x big angel fish, 2x smaller angel fish, 3x silver sharks and 1 albino shark so far...

Apologies for my ignorance on this lol just started out, only have generic lighting to light up tank, I have approx a 100ltr tank
