Just got back from a weekend trip to Pigeon Forge. Got a chance to visit Ripley's aquarium, it's been 4 years or so since we've been so things have really changed. My purpose for this post is to ask if anyone knows what they feed their fish because they were all beyond healthy - they were OBESE!!!! I will post up some pics later but man were ALL of the fish fat or what. The most apparent were their pacu displays. I am familiar with the Pacu species and I know these fish aren't suppose to be 10-12" wide and nearly 4' long. They looked like big floating brains or something. On their marine animals, namely the tangs I noticed that in about all of their displays (which were simply phenomenal) they had large clips of romaine lettuce. I've always heard before that this isn't good for the fish since it isn't in their natural habitat and so forth. But all of their colors were the brightest I've ever seen. Again, pics are forthcoming. Let's discuss romaine for our fish. I've fed it before and they loved the stuff. I only discontinued because of a post on RC that it was totally non-beneficial to them because their digestive system couldn't process it properly.
