Busy couple of days with the tank. A few days ago, I saw one of my fromia stars sitting on top of one of my Acans. I thought, cool, he's cleaning it off. Ate the whole thing, he did. I grabbed him and put him in the sump for indefinite time out. The next day, the other fromia was doing the same thing.
While poking around, I found three half-dollar size crabs. I made it my mission to catch all of them. Down into the sump they go.
From my FTS pic in the previous post, you may be able to see how the sandbed is a little low on the right side. The nozzle positions for the circulation pumps and powerheads pushed the sand around. I wanted to wait a few months until it all settled down. So, I added another 10 lbs of sand to fill in the area. The grain size is slightly larger, 2-5mm, and over the last couple of days it hasn't blown around.
