I think once these mats are actually covered in sand it looks more realistic than most in the way it comes out from the sand but the bright green is still too powerful. They should make fake plants that have a little bit of wilting to them... I wonder if theres a market for that... It looks more realistic than PERFECTLY healthy plants, thats for sure.
I came across this in a clearance bin at Michael's, so I picked a couple up just to see what it would look like as a background in a small tank. It's bright and fake looking and I'm not planning to leave it in for long, but this will give you an idea what it looks like. It looks similar to the one you linked to.
I can't comment exactly on the 'Fancy Plants' , because I bought my stuff for a heck of a lot cheaper over at Michael's, and I think it looks good.
The plants over in back right, and left are like Fancy Plants.
I like the stuff. It's good for small fish and fry to hide in. Mine isn't exactly like that but similar. Of course I think real plants look better but with mbuna I gave up on trying live ones. Also lately I've seen some pretty realistic looking plastic plants in varying shades of green (none really half dead looking lol but lighter and darker shades. I've also seen some silk plants used in aquariums that look really good.
