It is highly unlikely that any tree or shrub roots would poison the fish. However, some sealants would be very bad for the fish. The risk of using an old root you find in a forest is extremely small, so relax, clean it very well, and enjoy it. At worst you will get yellowish water from tannins in the wood, but weekly water changes will take care of that. Or, use activated charcoal in the filter to remove the color.
