* Sharp edges: Seashells often have sharp edges that can cut or injure your goldfish.
* Calcium: The calcium in seashells can leach into the water, raising its pH levels and making it unsuitable for goldfish. This can stress your fish and make them susceptible to disease.
* Decoration: Seashells are not a natural part of a goldfish's environment and can be stressful for them.
* Space: Goldfish need ample swimming space, and adding seashells can limit this.
Instead of seashells, focus on providing a safe and healthy environment for your goldfish:
* Large tank: Goldfish need at least 10 gallons of water per fish.
* Clean water: Regular water changes and filtration are essential.
* Plants: Real or artificial plants can provide hiding spots and enrichment.
* Smooth gravel: A small amount of smooth gravel on the bottom can provide a natural look.
Remember: Your goldfish's health and well-being are paramount. Providing a safe and stimulating environment is crucial for their happiness.
