It sounds like you have plenty on your plate. I am sure you will have more awesome scapes for us when you have the time and space for that again, but that is great to go out and do those other things. You should do as much of that kind of thing while you are young and don't have all kinds of obligations all over the place. What are you doing in China?
Yeah I was surprised to see those pneumatophores developing on the black mangroves too. It took a couple of years for the plants to grow to size and start developing the pneumatophores. I really want to get some red mangrove going as riparium plants and encourage their stilt roots to form. I understand that white mangrove will also develop pneumatophores. I have just one of those that's 18 months or so old and ~14" tall, but I don't see any pneumatophores yet.
