Tree branches for aquascaping?

[FireSpitter]

Was thinking of using the fallen tree branches for my scaping. Is this advisable and what should I look out for?

[Fei Miao]

I have used these for vivarium but have not try them in aquascaping, but these are few points you might have to consider,
1. You need to find some really dry branches.
2. These branches usually do not sink easily.
3. You need to remove the bark.
4. There is always chances the branches will rot or grow fungus, especially if these are throughly dry branches.
5. Chemical or whatever unknown substance from the branches might leached into the water and poison the fauna.

On another note: I have seen Chan from NA use some dried branches in his scape before...you probably have to treat it well before use.
