Reds (Rhizophora mangle) are the easiest to find, both commercially and out in nature. All Rhizophora species also have those beautiful prop roots we all like, unlike other common species such as white and black mangroves.
Salinity doesn't really matter much (or even full immersion in water); what is often misunderstood, is that these mangroves don't really need salinity: they rather adapt to a situation where water is salty, and they are among the fewest plants able to copy with it. But freshwater is perfectly OK.
As HX67 mentions, if grown suspended in water above the substrate - to stimulate root growth - they tend to "concentrate" their efforts on this, rather than on leaves, and they do remain at risk, in such a situation.

Well, I can tell you what is the season when I found propagulae in huge amounts in southern Brazil; and that's their summer, i.e. our winter. In months like September, I hardly found any.
I haven't yet found a paper indicating that they flower during a specific season. Especially in the tropics, temperatures hardly change seasonally (but rainfall does). Perhaps therefore in those regions they do produce offspring almost all year round, and that's why I always found propagulae on the trees. In the temperate zones, such as southern Brazil, wheres seasons do matter, my findings probably confirm that production may be related to seasons.
Commercially, assuming that what I said above is correct, availability will depend on origin... Buying from the USA will probably give you mangroves from Florida.
www.mangrove.at is a very good source of info - and propagulae!

Oh videos would be lovely! Underwater photography is something I'd love to get into (but at the moment I don't have the money) so it's always nice to see other peoples stuff
