I saw this in a saltwater tank and was wondering if I can put it in my fresh water tank? Its some dead coral skeleton I think...

Unfortunately, placing dead coral into a freshwater tank will change the water chemistry quite drastically. Unless you want this, I would skip out on this decoration.

Dead coral will add sodium and calcium into your water, thus messing up its chemistry. The shape of this coral is very similar to Manzanita Driftwood, and I would recommend that if you want a similar shape.

some how I kinda knew, but I was hoping I was wrong. That could of been a nice bonsai looking piece.

Thank you for your response.

It looks like a black coral skeleton. I had one in a freshwater tank for many years. If you soak it in a bucket for a few days the sodium will disappear pretty quick. Calcium carbonate is not very soluble though it will add some hardness to your water. For a tank on the alkaline side you won't get much calcium. If you have fish or shrimp that like alkaline water a little on the hard side, you have no issue.

If you run an acid tank with soft water, it would not be compatible with your water chemistry.
