If you want a true Iwagumi you'll need some larger rocks to have as a focal point. That is where I would start because hardscape is super important.

maybe i need to add more soil on the backside also between rocks to look more naturalI think that is better, the rock size and choices are good, and for the most part placement as well. Although something about it just seems a bit unnatural to me. I'm not sure I like the empty space in the middle. BTW I think you have enough space for plants don't worry.

thank you opare, the more expensive is okay for me ,do u think RGB will effect the same as A series for green plants such as hc and Hg ,?Any light will do TBH, so go for the Chihiros A Series over the RGB, cus I know the RGB is quite substantially more expensive.
The RGB is better for colour rendition (for red plants etc.), but since the HC and DHG are green you don't need to worry.
HC is a pretty undemanding plant in terms of light. Just make sure it gets decent flow and CO2 and you should be fine.

The A-Series will be completely fine. It can even give good red and non-green colours, but they would look better with the RGB light. Since you just have green plants I would go for the A-Series. Also, the A-Series is dimmable, which is good, especially for Iwagumis you want to make sure you don't blast light, since you don't have many fast growers. Not sure if the RGB is dimmable.thank you opare, the more expensive is okay for me ,do u think RGB will effect the same as A series for green plants such as hc and Hg ,?
yes the RGB is also dimmable , will one rgb( 50watt ) enough for green plants or i should add another white led as well ? just wonder if rgb effect the same as A for green plants because fish look much better in RGB leds also maybe in future i add red plants .The A-Series will be completely fine.

If you plan to rescape the same tank and use more colourful plants maybe the RGB is something to consider for the future.

I too was trying to decide between the Chihiros RGB or the A Series Plus, in the end I went with the A Series Plus, was unsure if the RGB really puts out a lot of light, I have a 45cm A Series Plus already, that light is seriously bright, and because I plan to have a 45p and 60p next to each other I decided both should have to same light.im stuck choosing the right light , does RGB led better for growing hc cuba rather than normal led?
there is chihiros a plus with 65watt and new chihiros RGB 50watt which one do u think would work better for growing hc cuba and hairgrass for this tank?
