Why wood selection matters
Aquarium wood should be sold for aquarium use and fit the tank without sharp edges or unstable stacking. In a shrimp-focused aquarium, the choice should also support steady routines, visible livestock, and access for basic care.
Before you act, check the source, condition, dimensions, and any treatment or coating. Compare the item with the rest of the setup and note any recent change that could affect what you are seeing.
A careful way to proceed
rinse and prepare the piece as directed, then place it where it can be observed. Make one adjustment at a time and watch how the aquarium responds during normal observation.
Avoid using decorative wood with unknown chemicals or finishes. Labels, products, and tank conditions differ, so use a reliable guide as context and record what you directly observe. If uncertainty remains, ask an experienced shrimp keeper before making a consequential change.
Use these as general hobby references. Test your aquarium and confirm product guidance before making changes.
