I got some lava rock from a landscaping place for the flower beds and was wondering if it could be used in a fish tank? Its the stuff that is like red colored and kinda porus looking.

I would say a big yes providing it is cleaned
Just to be on the safe side I would like to see a photo.

I would soak it for a few days, hose it clean to remove all the gunk, a clean scrubbing brush will also help then boil it if you can size permitting.

Check with Frank first to be on the safe side.

I've read that you can use it in 'scaping your tank, but be careful. If you have bottom dwellers that like to burrow or wiggle into crevices, it can be too sharp or rough. It's recommended that you grow algae or moss on it to keep from injuring the fish. *shrugs* At least that's what I read.

In fact, they sell lava rock in pet stores for putting into fish tanks, and your stuff sounds like the same stuff.

I've never used it though because of its roughness (and also that rocks at pet stores are way overpriced).

The aquarist is one who must learn the ways of the biologist, the chemist, and the veterinarian.

I think the stuff you are talking about is called scoria. I know people use it as biomedia, so I assume it'd be fine for scaping provinding your fish aren't likely to slice themselves on it.
