Tank does look good. Be careful of those galaxys. Im sure you have found that out already but there sweepers are long almost a foot. I had the same blue one. It was one.of my favorites but really didnt have a good place for it it killed a frag or 2
Just watch were the sweepers. They are very noticeable on them. If you see them hitting some thing you can use your flow to manipulate them so they dont hit the coral next to it
