What’s up with my Kenya Tree

[Nanorock1970]

I have been noticing my Kenya Tree has a branch that is inflated. I have also noticed that some of the branches have narrowed down and not a uniform thickness like other branches. Is this normal? Is it a sign to keep a lookout for floating Kenya?

Thanks for your input.

Looks like it's about to detach. This is how they propagate.

That is what I was wondering. I knew the branches “break” and drop to spread but this is the first time since I have had a Kenya tree that I have seen this. I know I want to collect the frags so they don’t spread to anyplace they want....
