I went there last year. It is crazy the amount of care they have at this place. I do believe when you watch the penguin display. They say that the water is all circulated from the Atlantic. So they have all the water they need to keep it clean. Bottom line. It is a place to take kids and have them see the world out there that they can not get to yet. There is no reason to call PETA or think they are getting paid under the table to let things slide there. Your point about some fish eating corals. They don't NEED to eat corals. It is just something they do. It is all about them getting their diet. In the video I would say yes they highly do, because this not a bunch of people that have no clue at what they are doing. The people were hired to care for this to the highest level. Can you imagine the cost of a tank crash of this proportion. This is not people who buy an API test kit and shake a couple 5ml vials. Say everything looks good. Let's go home. I feed my tank 3x a day, but I know I don't take care of fish. I take care of water. That is my job/fun for me. They just be fish in the water I provide for me to enjoy and educate people about it when they come over. Same concept, but theirs is 5000x larger. Let's all just hug it out. Leah you had a concern. That's fine. Just need to reword what you say so it doesn't have a lost in text moment.
On a side question. Did you enjoy your time there?
That main central tank. I don't want to give any spoiler alerts, but wow! The angels were huge! The puffers too! I would highly recommend anyone going there.
