Not the best pics but this is what I ended up with for the large blue piece that I believe is some type of tort. I went with the lower placement vs the taller one. The past placement had the tips growing out of the water. I'm hoping that once I fill in the gaps it wont appear to "block" out the back rock/pieces.
The back of the tank needs to be scraped too, I will remove all that coralline so its all black, its a much nicer look staring into the abyss
