Artificial rock cave??

[phillipsjo21]

I currently have real texas holey rock in my aquarium but I was thinking of adding a few more fish and also wanted to add a few more hiding spots. My rock setup now is pretty much how I want to keep it so I thought I could add some basic rock caves. Had anyone had experience adding artifical rock caves from the pet store like the ones attached? I don't want it to interfere with the water parameters. Thanks.

Fwiw, I’ve found that the natural rock formation usually creates plenty of hiding places, some that I can’t even see! But those caves sure are cool
