Yeah, Even when the diving instructor walked past and said "please dont feed the fish" they waited till he had gone and simply carried on. Its nice to see other sharing there knowledge especially to younger children such as the way you do with your grandchildren. IMO, the public aquariums help to. I know that The Deep which is about 1 hour away from where I live allow school visits and they organize other events where people can come along and learn about the fish and I think they even have a touch center but I haven't been in years so things may have changed. Its a very good thing to pass on because it teaches respect for the ocean and all its creatures.
