hey i live in mobile, and i often fish Horn island and Pettyboy. I know a guy who got some live sand from the east end of horn island, he waited for a good incomming tide and planed his trip so he got there about an hour before high tide, (water from the gulf should be pretty clean, where as water from the sound????) he had all kinds of stuff that showed up in the tank (im not a saltwater guy, did not know what they were). I have a 16' trall net that we use to pull for bait and we catch a bunch of stuff that would look great in a tank, seahorses and the like. there are some old stumps about 1/4 mile west of the east end of horn island, I pulled one up several years ago with an anchor, would something like that act like live rock?
