Local Driftwood

[sto0ka]

Hi,

Few months ago I found nice driftwood branch in local river. Took it home and forgot about it.
Last night I took it and kind of made miniature tree out of it.

Would that be aquarium safe?
I'm planning to boil of for an hour, and cover branches with moss balls to create realistic tree.

Type of wood I believe is elderberry tree.

Update: googled a bit dried elderflower, and it doesn't really look like it.
Here is rest of that branch

Looks like a soft kind of wood to me, which if so will disintegrate pretty quickly when submerged. If you can stick your thumbnail into it and leave an obvious mark, I'd call it too soft to use. Also an hour of boiling is a bit overkill. Lol. If it has been out of fish-bearing waters for a month, it won't harbour any pathogens. Glueing it to the rock will take care of the floatation problem. Boiling too long will make it disintegrate faster.

It is hard as rock from the outside, but center is soft, if you look closely on last picture you'll see what I'm talking about.
