Yes I just have those up until I find something I like also going to do black curtain rod and finials. Have to wait on rug as we just had hardwoods refinished and they suggested to wait a couple of months before putting an area rug down.

First, open your French door to see how far it extends without hitting your tank. Move the tank as close to center on the wall as you can. I would then explore art that contains aquatic images. Koi fish, sea turtles, etc. Something fun for your fish to admire as they swim in their tank!

You could do something sculptural, but I like the idea of more colorful art like you have on the other wall. You've got so much brown and neutral colors, some more color would help make the room less one-note. I'd even consider layering an area rug in that space for the same reason.

I created this mock up as a concept for this space. You can pick different styles but these are elements. I couldn’t orient the fixture and table properly due to limitations of software but the table would sit length wise along window and the linear chandelier would turn lengthwise over table too. Do 3-4 mirrors rather than whole wall. TIP: smaller mirror tiles are extremely difficult to place on wall effectively. Leveling, imprecise sizing and wall surface make mounting a very time consuming and difficult task especially on that size wall. I would not recommend it.
