Thanks for the info.
The Dogfish was given to me by a shrimp collector while I was at Fin-Addict. Yes, he's Texan.
I also keep a 90 gallon freshwater tank which is full of plants, rock, clams, snails, and other stuff I pulled out of the Comal River. Everything but the fish (two Oscars and a Plecostomus) are Texan.
