So basically one of the ways to integrate the three tanks (besides the substrate levels and overall topography) is creating some level of continuity on vegetation.
I have some basic ideas in regards to greens and reds, but I am not married to any concept.

You are, by now, tired of seeing this one. But please keep the topography in mind.
When you add plants to the equation, substrate becomes less obvious, so you do have to rely on other aspects to create the trinity effect.
Here are a few options. Please note that the foreground can either converge to the middle or spread from the middle. That's something I need help.
If we focus on the central tank, the front grass can go out, becoming bigger on the other tanks
Or the other way around, where the side tanks will look more bushy with less carpet.
Any ideas?
