Isn't it odd that we see many Amano aquariums with well-developed stands of Fontinalis antipyretica and yet I rarely if ever see it for sale (not at Tropica, for instance) and never see it discussed. It's a mystery compared to Vesicularia dubyana, 'Taiwan', and 'Erect' mosses.

The Fontinalis antipyretica used in Amano's tanks are, I suspect, just good ol' Java moss. The only Fontinalis species being sold every now and then is actually the giant form, possibly Fontinalis antipyretica var gigantea, which is considerably larger than any of the common moss we're familiar with.
