Mermaid art in home

I have two mermaid statues on my dresser and mermaid artwork hanging on the wall in my bathroom. I live on an island, love the beach, and grew up boating. Mermaids are fictional and just a symbol for my love of the water. Now that I am going through OCIA and my home is slowly collecting more Catholic art and items, I’m wondering if the mermaids really should go. Thoughts?
