any ideas on decent /colourful marine plants??
I honestly don't know that there are too many plants as such, there's a few macro algaes out there, but generally they don't go in the display. Plenty of 'weeds', I've had few hitchhike on my LR, but I actually havne't seen any for sale in LFS etc.
Most of the 'plants' I've seen wouldn't be suitable for captivity (they grow too big), and aren't very colourful anyway. Maybe a quick google on "marine plants" ?
Corals add the most colour, but given you're looking at FOWLR, probably not the best answer.
EDIT: Here's one marine plant I've found: https://www.fishlore.com/fishforum/marine-plants-macro-algae/57067-real-marine-plant.html
