Just ran over to my local Wal-mart and walked through the fish section. I prefer to avoid buying from Wal-marts in general, although to be fair the one they just built here in Mooresville, their tanks seem pretty well taken care of, waters clear, colors good. I see fish and then I come back a few weeks later and I see that fish again still alive. Maybe they've got somebody working in that department that cares I don't know. Anyway they have a dragon/ violet Goby which I've seen them have before except this ones 1' long at least. Mouth on this guy is huge. He makes me wish I had a brackish tank. Another surprising thing they know he's brackish, and hes labled that way. Half the employees at Uncle bills (our chain fish store here) don't know what brackish means.
