Not a big fan of Petsmart plants. Most plants you get from there, especially the swords will melt away so it doesn't matter if you get a large or small as all the leaves are gonna melt away and regrow. I've had luck with some plants there, especially the stauryogene repens, but there are way better sources for plants. I've sworn off Petsmart for both plants and fish. Their filtration sucks and large groups of tanks if not all of them are connected so diseases spread so easily, the fish aren't quarantined properly if at all, the specimens aren't always that great, 90% of the people there have no idea of what they're talking about. I could go on and on. I know some Petsmart's are better than others and some people don't have a decent lfs nearby but I refuse to put anything alive from Petsmart in any tank I own. Thats just me though.
