I love it. I think there are lots of cool ideas using this technic. Some will want to make it look as natural as possible and other, like me, will create an ancient city with columns and such.
i personal don’t like the fake corals. I love sculpting with Marco rock so much better and seems so much better for the tank.
and I think what’s important is having spaces for the fish to explore and have their own safe space. If we provide a healthy habitat for the fish and create an artistic aquascape it’s a true win win.
