Steps to Introduce into a Fish Tank
How to Safely Add This PETG Decoration to Your Aquarium:
Inspect the Item:
Ensure there are no loose strings or sharp edges. Sand lightly if needed.
Rinse Thoroughly:
Rinse the decoration under warm water (no soap or chemicals) to remove any dust or residue.
Optional: Soak in Tank Water:
Let it soak in a container of aquarium water for 24–48 hours. This helps to equalize temperature and water chemistry.

Gently place it in your tank. Avoid pinching live plants or trapping fish.
Observe Fish Behavior:
Monitor your pets to ensure they interact well with the new decor. Most will begin using it as a hideout shortly.
