Can you put Crayola air dry clay in a fish tank?

Here's why:

* Toxicity: Air-dry clay is not designed for aquatic use and may contain chemicals that are toxic to fish. Even if the clay is non-toxic, it can still release harmful substances into the water.

* Degradation: When clay gets wet, it softens and can break down, releasing particles into the water that can clog fish's gills and cause health problems.

* Water quality: Clay can alter the water chemistry in the tank, making it difficult for fish to survive.

* Bacterial growth: Wet clay can become a breeding ground for bacteria, which can contaminate the tank water.

Alternatives to Clay for Tank Decorations:

* Ceramic or glass ornaments: These materials are safe for fish tanks and can be cleaned easily.

* Live plants: Live plants provide natural filtration and add oxygen to the water.

* Safe, non-toxic plastic plants and decorations: Choose decorations made of aquarium-safe materials.

* Rocks and driftwood: Natural materials can add a natural touch to your tank.

Important: Always research the safety of any material you want to use in your fish tank before adding it. You should also ensure that any decoration you use does not pose a risk to your fish by having sharp edges or small parts that they can swallow.
