Here are some pics of rock that I have made. The first pic is some of my oldest rock. Made last easter and in tank since late July. Piece to left is a large cave, and the piece to right is actually "fish" shaped, tail in sand. O.K. looks kind of like a fish. Third and Fourth pic is a new rock made in January, again a cave and fish, now you can see the fish, right. The last pic is of a rock I made last year. Hanging out in my frag tank at this time. Just wanting to share, got most of my idea from GARF website.
