[PHOTO] Twenty-four more photos of Ripley’s Aquarium
This is the third and final photo post from Ripley’s Aquarium, following Monday and Tuesday.
The last portion of the tour through Ripley’s was, for me, perhaps the most memorable. The clownfish, the lionfish, the cute cuttlefish (look hard!), the scarlet cleaner shrimp manicure and the bamboo shark petting, the complex life support technology, the glowing jellyfish—all stood out. Even the goldfish in their neat clean tanks inside the entry were worthy of attention, and memory.

[PHOTO] On the giant silver koi, and other goldfish, of Allan Gardens, Toronto
Long-time readers of the blog may remember that, once upon a time, I had goldfish. I enjoyed them, with their happy swimming and their responses to me. Even now, I still own the empty tank that they once had. When I go to Allan Gardens, I usually head first to the south wing and its goldfish pond.
My favourite fish there is a standout, a great large and strong silver koi.
[URBAN NOTE] “Discarded goldfish are taking over Hamilton’s harbour”
The descendants of abandoned goldfish, CBC’s Samantha Craggs notes, are populating Hamilton’s harbor.
Researchers at the Royal Botanical Gardens (RBG) have counted as many as two million large and small goldfish this year, fish that are likely descendants of people dropping unwanted pets in the water.
Now there are so many that they’re throwing another wrench into attempts to rehabilitate the bay.
This year, the RBG team has counted as many as 2,500 large goldfish and two million young, said Tys Theysmeyer, head of natural lands with the Royal Botanical Gardens (RBG). They seem to be thriving thanks to climate change, and poor water conditions that have discouraged native species from flourishing.
RBG spotted handfuls of them dating back to the 1990s, Theysmeyer said. But lately, the problem has worsened.
“People used to actively release goldfish into the bay a lot,” he said. “In the last five years, their numbers have been rising and rising.”

In Hamilton, the numbers are rising from a perfect storm of water conditions. Warmer water temperatures mean that new fish species such as the goldfish can survive, where decades ago it might not have. Theysmeyer says pressures on water quality in the bay, such as contaminated overflow from the city, have also caused a decline in native fish species, leaving more room for goldfish.
Native fish such as northern pike, freshwater drum and several sunfish and minnow species are in short supply, Theysmeyer said. He estimates that only two species — namely yellow perch and blue gill — are showing up in greater numbers.
