Why leaf damage matters
A hole in a leaf is an observation, not a diagnosis; plant age, damage, and growing conditions can all affect appearance. In a shrimp-focused aquarium, the choice should also support steady routines, visible livestock, and access for basic care.
Before you act, check whether the marks are new, spreading, or limited to older leaves. 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
photograph the affected plant and compare its new growth under the same conditions. Make one adjustment at a time and watch how the aquarium responds during normal observation.
Avoid treating a single hole as proof of a specific nutrient deficiency. 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.
