And the winner is..... the brain coral by 4 lengths. Late last week I put the coral/rock back where I wanted. This morning it's back up against the front glass. Been watching it to figure out how fast it moves - Sunday night to Monday morning - 1/2". Monday morning to Monday night - 1/4". Monday night to this morning the remaining 1/4".
I'll try to get some pictures when I get a chance. Too busy floating down the river after work.
