That is 100% false. @Retired Viking can back me up... lately, his Anacharis has been failing him and dying. There have been a lot of posts about people having problems growing Anacharis.
I haven't had much luck with anacharis, either. It, mostly, survives, but it doesn't really grow. I want an anacharis and milfoil jungle with some java ferns and crypts, but I don't dare spend any money on them because I'll probably kill it. I did buy some guppy grass from a member of another forum, but it was shipped during 90+ temps and no cooling packs, so it didn't make. I definitely don't want a repeat of that. I'm just doomed to mostly artificial plants and hardscapes with my cichlids because they destroy everything.
