894480 2X-Large Texas Holey Rock

I put the rock in a 20 gallon extra tall tank it looks good.My fish can hide inside.Light weight plastic will not crack your glass tankand it is heavy enough to stay on the bottom..It looks more natural with some algae growing on it.Made for fish tank use, did not poison my water.(I had tried floral glass for gravel and it made my water alkaline)Good product, not cheap but you will have it for years.

Realistic looking. Dense enough to sink easily, but not too heavy. I think it would be tough for anyone to tell that its not real Holey Rock. It was packaged really well, however a small corner broke loose. Not a big deal for me, because it came off from such an inconspicous place that it doesn't change the apperance at all. My biggest complaint is the dimensions. Shorter by 2 inches in each dimension advertised. Mine is 18.5 inches tall, advertised at 20.5 inches. I wanted the tip to poke out of the water. I guess I will have to find a rock to put it on and pile up the substrate. Incorrect dimensions is inexcusable when you are selling something online. I wish that there were some partitions inside, inside it is one large hollow cavity. It would function better as caves if there were some septations inside the hollow body.

Very nice

Looks amazing, especially if you have the other holey rock pieces. Looks very real and so far I have no complaints. Make sure your aquarium is tall enough if getting the XXL.

looks great in fish tank

awesome product
