Because I'd never led off consecutive posts with fish images ...
Actually, having the experience of one trip behind me, and knowing that the bulbs I captured last Saturday would actually open up later in the week -- and during a warm afternoon sun -- I returned to the show to capture more (and, thankfully) satisfying images, including the fish in the two koi ponds.
I wondered whether they should rename the ponds "coin" ponds, there were so many spots loaded with "wishing well" coins. Part of the challenge of capturing fish images there was positioning the vantage point to reflect the fewest amount of coins, but it was nearly an impossible task. All of the coins in the photo above, and most of the ones in the other fish picture in this post were erased in post-processing.
The bulbs -- well, tulips, primarily -- indeed were open on my return visit, and the light hit the flowers in both the glass atrium area where the spring bulbs were displayed and the tropical plant display in the temperature-controlled main section of the Garfield Park Conservatory in a most splendid way.
The image of the crocus plant below (purple bloom with orange-gold stamen) actually was outdoors, right outside the conservatory's main entrance.
