black vs red mangrove

The Red Mangrove, Rhizophora mangle, is a species that does happen to be somewhat different from the Black Mangrove, Avicennia germinans. R. mangle takes on 95% salt water, and the other 5% gets stored throughout the tree. While A. germinans takes on 100% saltwater, and expels it through the leaves, to let rain wash it away.

Beside the facts that they're two different species AND one stores salt, while the other expels it, no. There aren't HUGE differences. They are still differences however.

Interesting differential. Any reason why a hobbyist should prefer using one over the other?
 
Red Mangroves are more naturally suited for growing in the environment of a tank/sump. Floating propagules, prop roots, happily growing from the water's surface all the way down to the sand-bed. I believe it can still be done with Black Mangroves, but they are more suited for marsh or shore growth, as they don't grow prop roots and grow from seeds rather then floating propagules.
