1) I see you have a black mangrove growing. I have a couple of fresh seeds I never dared to plop in (low-end brackish), because I'm not sure it would survive in plain water (unlike my red mangrove propagule, which are indeed rooting quietly): so, how is yours settled?
2) I see you have a number of epiphites (the carnivorous and many tillandsiae, in different tanks): I tried myself with some micro-orchids and many tillandsiae, but many of them didn't make it: some look too dry, and some like rotting due to eccess of humidity. I can't figure which of the two... So, what are the humidity conditions in your tanks? Are they sealed?
But my black mangroves seem to be doing swell in a Riparium Supply planter. The propagules seem to need a ground (I have sand in the planter) to start rooting. The propagules I planted on moss or other wet spots, died without any sign of life.
I have a feeling the red mangroves are not that salt-tolerant after all. Well, I just have never seen a lush plant living in a saltwater tank.
The one I had, rooted well and started growing ok. But soon, without any change in conditions, the growth stunted and eventually they died. All of them.
In the wild the roots of Mangroves are deep in the sediment. I have a feeling the water is not salty down there.
I mean, they do start growing, but pretty soon they need fresh water... I don't know.
Please, anyone, show me a pic of an older mangrove thriving in a salty tank!
hi i jus wondering what some speices that will grow in my aquarium that are large enough to grow well out the of the top of the water, i dont mean standard plants i mean ones that are meant to have its leafs out of water, i have an open top aquarium and a large empty space above the tank were the light system hangs from the ceiling i want to fill this out with plants aswell like yours
Cheers, HX!
That's exactly my doubt: mine is an aquarium 100%, with sand at the bottom. The red mangroves are hanging by one side, and slowly developing their roots. I'll try to follow A. Calfo's suggestion to raise part of the roots out of the water, since this apparently stimulates the extended roots typical of this species. But the black? Can I just plop the seed in the water, and let it stay on the sand? I understand yours are in open air?

I'm pretty sure I've seen relatively large red mangroves in reef tanks. And they can surely live in full marine conditions in nature. I'm collecting pictures of mangrove environments, if you want to check them out. My tank is a low-end brackish, so this should not be an issue. Sure issues are movements (they get very upset if you move them after rooting in the ground), and high sensitivity to pruning (premature pruning can kill the plant).
Agreed on orchids. My Schoenorchis is doing barely ok under direct light (and that might be the problem), and definitely it doesn't get wet.
Great advice on Tillandsiae, many thanks! Mines are collected in Brazil in various environments, no wonder they're reacting differently... I'm going there again next week, planning to spend a weekend in a mangrove estuary, hopefully I'll get a few more reds!
The early pages of my (B)log, below, show how I set the aerial plants at the beginning (autumn last year). Not many of them are left...
Are you in Finland?! I'm in DK.
Cheers!!

I planted the black mangrove propagules in wet sand, in a Riparium Supply planter on the surface of the tank. I don't think they do well if you just put them in water.
I know that mangrove grows in full marine conditions, but what Im trying to say is that their roots go deep into the bottom substrate and there are no small roots in open water, no?
This leads me to believe that they actually get the moisture and nutrients from much less salty conditions than pure sea water. I could be wrong here...
I envy your collecting trips, dude.
You gotta give us a photo lecture of those.
Nice blog you've got going there.
Yes, I'm in Finland.
Love those Danes. The happiest people on earth.
Right, as I expected. So it's a no go for my black mangrove seeds. Fair enough, will get more reds!
I see the point, but I'm not sure how salinity and nutritive contents change in the substrate. But there ARE new roots coming into the water, so at least at the beginning of their life these roots do have to cope with high salinity. Some of these roots actually come down from high branches, rather than from the body of the tree.
Yes, I know I'm a lucky #19### on this. I'm in Rio again right now, will spend next weekend in a new river estuary I recently found, not too far from town. So, new pics soon. If water conditions allow, I'll get some underwater pics, I have the diving case with me this time. How about you, where do YOU get your plants from?? Should I find enough propagulae (and be able to smuggle them!), do you need more?
The Danes! I love them too. I'm myself italian, moved to DK some years ago, just because I wanted to be there.
Nonono. There's ample space for a planter on the surface, behind those magnificent roots in your tank! Either a hanging planter or something supported from the bottom (a 50 mm pipe drilled full of holes, perhaps?).
I agree, in the beginning of their life mangroves take all they need from water. But once the roots reach the bottom, the small roots vanish from water and more mature trees only have thick roots going into the substrate, no?
I don't have data on the conditions in the bottom substrate either. Just a strong feeling... At some depth salinity lowers and vanishes for sure. But do the roots reach that or not? Anyone?
