This certainly doesn't cross any OT 'lines!' No worries on that, unless you ask, "which store has the best T shirts at the various aquaria you have been to last Saturday?" Stuff like that
This is basically reefkeeping on a larger scale.
I throw out a list of aquaria I have been to- that I can remember, LOL- and perhaps it will jar the memories of people
I generally like all aquaria, so I am not the best person to ask...there is usually something unique about any of them. I love them all
Shedd Aquarium (Chicago) (new home of Sterling's basket star, if they are taking care of it!)
Aquarium of the Americas (New Orleans)- has a 'rig' tank which may be the 'under water' part, basically showing life around a drill platform in the gulf.
Monterey Aquarium (CA) simply fantastic
Steinhardt Aquarium/Scripps Institution of Oceanography (CA)
National Aquarium (Baltimore, MD)
Mystic Aquarium (Connecticut)
New England Aquarium (Boston)- this is one of my favs, I like the design, and generally have good memories of it...except for the big dig going on)
Texas State Aquarium (Corpus Christi, TX)
Moody Gardens (Galveston, TX)
Downtown Aquarium (Houston, TX)
I know there are others, but I'll have to ponder that for awhile.
