Sorry Malika, I don't know where I found that painting. :-( I just copied the image from the google images search I did. Maybe type in the exact wording I mentioned in my post earlier and see if that image comes up. I don't know if it's the perfect painting for your room, I just picked it because it was one of the first paintings that caught my eye. I liked that the colors in it were softer and more muted, yet was still very colorful which you seem to be drawn too. That's too funny that I imagined you having a betta and that's what you have! Lol! I was actually thinking you meant a bigger aquarium fish tank. Best wishes.

That is precious! How about a round table with a table lamp? This one may be too white. https://www.ballarddesigns.com/georgia-round-side-table/furniture/living-room/coffee-accent-tables/479501?listIndex=61

Instead of the little round table, you need a larger square one that will largely fill the space and be at or just below the height of the arms. Then you'll have plenty of space for a lamp as well as for everybody to set a drink. You didn't ask, but I'd add an area rug to ground the whole seating area, and probably a coffee table in front of the couch too.

Can you clarify if you are referring to light stain (natural) wood or white and dark brown stain or black? I see natural wood and black as more modern; white as country or coastal, and dark wood as more traditional. Again, just my opinion. Any color will work in your space, it’s just a matter of your style. Are you keeping the chandelier? If not, maybe find the light that speaks to you and then find the furniture?
