I've seen many tanks with lots of cards, but most of the cards are so so, they are really healthy and active, makes it a lot nicer to keep. Folks generally like them for their coloration........I like most fish for behavior first, then the coloration second or some finnage etc.
Nice when you get both.
The other thing is this foreground plant roots aggressively, so the plecos do not uproot it, I tried HC after moving, it never got rooted enough to make a go. I did not want hair grass for this tank.
