New Member - Stocking ideas

Hi,
New to the Forum.
Been keeping fish off and on for about 30 years.
Done most sorts of sets ups over the time period.
My current tank is 550L (150cm x 60cm x 60cm).
Had some silver dollars and a few other bits and pieces in there, but am bored of it.
So am thinking of doing a Lake Tanganyika theme - never done one before. Mainly smaller to medium species.
As for decor, I want to do something a bit different to the piles of rocks one usually sees.
What I would like to do is piles / tangles of wood and some hardy robust plants.
I live in a hard water area - KH around 15 and ph 7.8
Haven't measured it in years. But it's somewhere around there.
Was thinking of stocking etc.
Not too sure what the best combination would be?
From what I have read it's a bit trial and error.
Anyway, looking forward to hearing from other members
