Please give me feedback and any suggestions. I want to center it in the tank but not have many sharp edges. I like the idea of ramps that the fish could swim up. It may be far stretched now but I am going to change it.
So here are pictures of the tank ornaments that my mom has in some of her tanks.



I like this one the most, where the sand fills in the area and it creates sort of a shelf that the loaches lounge on. This pyramid will incorporate sand filled into it. So the pvc pipes will be buried. I may even place a few plants at the top in the sand directly next to the columns. This is all up in the air now but thats the general idea right now.

So the side would be angled with pvc pipe cutouts. And the sand would be filled like this. But there would be a ramp up on the side with a columnar house on top.

This is an interesting one

The idea is to make this look like a Mayan Temple. I looked at images of many temples and I am trying to design the structures to be loach friendly. Any help or criticism is welcomed.
Here is the initial concept for the tank ornaments.
