This is sort of good I guess for some enrichment, but I went to the Vancouver aquarium a decade ago and it was sad. The dolphins /whales in the tank just did the exact round trip of their environment over and over, with same twist , rollover and turn every time. I watched for half hour and it was an unbroken loop of the exact motion. Those animals were losing their minds in there. When family came to visit and insisted on going I just dropped them off and said call me when you are done and just drove around Vancouver for an hour. I couldn’t see that again.
