Yea the first two pics are the same nem. I was told that it was a bubble when I got it. There are so many its hard to keep up with. And your right the other nem looks just like a condylactis anemone. Same colors and everything
Would there be a way that we could add sand to the tank? If anyone knows some tricks I would love to know them.
Make sure it's wet first. Get a PVC pipe and a big funnel that slides down into the pipe. Flexible hose works too, but is more likely to jam up at the bends. Turn off all flow while pouring sand in. Hold the bottom end of the pipe about an inch over the bottom surface and pour into the funnel.
Yes. The sand bed.
