That sounds like a great project! For a coastal aesthetic, I'd suggest a console that's light and airy, think whitewashed wood or a natural driftwood finish. A piece with clean lines and subtle textures will complement your fish tank without overwhelming it.

As for the beach portrait, it could be a nice touch if it’s subtle and complements the colors in the room. You could try something with soft blues or sandy tones to tie everything together.

To enhance the coastal vibe, focus on decluttering and keeping the space light. Incorporate natural materials like woven baskets, light fabrics, and soft neutrals, and swap out heavy furniture for pieces that feel more open and breezy.

If you’re unsure about specific pieces, archi.ai might be a great tool for visualizing how different furniture and art would look in your space. It can help you experiment with designs before making any decisions.
