I fully agree! As flashy as saltwater tanks seem, they are usually somewhat bare compared to our heavily planted tanks. There is essentially no saltwater greenery, and their tank colors seem almost cartoon-like compared to ours. Both can have their beauty, but take a look through some Amano pictures if you doubt the potential of FW.
my 12g nanocube has plenty of greenery in the form of some fern like and bubble like macro algae.
as far as this tank goes... I'd go freshwater w/ canisters since it isnt drilled. I'm setting up a drilled 125
and doing fresh because I don't want to spend the money setting up a reef tank. but, i bought drilled in case I change my mind down the line.
