Maybe add some of your experience's with each species and their behavior with live plants. (I see quite a few in some of the photos)
I personally never kept plants with mine so I don't have much input there.
Tangs off all types excluding tropheus sp and sometimes not even them, have NEVER bothered my plants. If anything The water you have to keep tangs in is what hurts the plants!
But when you keep tangs they are so expensive the plants you can afford are cheap and there only purpose (at least for me) was helping the water quality.
Plants I kept with all of the above fish (including tropheus and eretmodus) were Anubias -nana, barteri, coffeefolia, and petitie. Java ferns narrow and regular, vallisneria americana and spiralis, and cabomba.
My water for my wild tangs was basically liquid rock. PH above 9 and GH and KH in the hundreds...
The main reason IMO that any plant survived was the fry food 5xs daily. Just about every tank I had plants in also had fry. I feed my fry 5-6 times a day. This was the only fert introduced into any of my tanks.
Also lighiting was um... can I cuss here? It was BS. On my 125 gallon I had 40 watts of flourescent light I think at 10k. Ph 9-9.5 and GH and KH I don't even want to tell you guys... but I had Vall americana, Java fern, and anubias nana in there. Growing not just surviving...
