I was looking at doing a Tanganyika tank a while back, so I was shopping around for rocks, and Texas Holey Rock didn't look that nice to me personally. It looks too 'fake' for me. I suppose it would look alright in a marine tank, but I wouldn't ever put it in a freshwater tank for aesthetic reasons.

Sorry for the small picture, but I like these:

The red and orange ones anyways, not so much the blue.
I'm not sure what they're called though.
