I would add a bunch of rocks for their health and comfort, even if you do formal scaping later. Algaemax.
Thanks for the suggestions mate. I do have some small seiryu stones and river rocks from my previous aquascapes lying around and I will add them to the aquarium.
Algae max or
New Life Spectrum Probiotix
or both.
Thanks for the recommendation mate. The NLS Probiotix stuff is available too. I will pick either of the two for now, depending on the shelf life left.
