Holy pleuthora of volcanic whiskers batman! Thats crazy!! LoL! Gotta have some serious agitation or something going on in those tubs, thats a lot of fish to give oxygen to, even if they are able to breath atmospheric oxygen.
no doubt. they must have a constant flow of freshwater going through those tanks. i could walk across the top of the fish. i wander where they get those big blue tubs. i would like to get one.
