I took the kids to Underwater World and the Rainforest Cafe at the Mall of America yesterday. The Rainforest Cafe was cool, but the reef and saltwater fish (excluding the sharks) at the Underwater World was very disappointing. And yes, I do mean VERY disappointed in the reef tank (yes, essentially only 1 tank) their. Their reef tank was small for public aquarium (125 gal) and contained mainly a large
cabbage leather and a couple small LPS corals that were in rough shape. Virtually all of our tanks blows their tank away. They did essentially have a second tank, but it was probably around 50 gal and contained mainly aiptasia and LR. As far as the reef fish kept in their large fish display, the fish were about the same size as the ones you can purcahse at Olde Towne. Yes, larger than the typical store, but definitely not full grown adult fish. The kids did love being able to pet the sharks at Underwater World and being able to bring back a sticker that says "I touched a shark" to show to all of their friends at school. We actually had to go back through the Underwater World a second time again later in the day so that they could pet the sharks and stingrays again.
As for the Rainforest Cafe, they had some great displays containing saltwater fish. The tanks are large and contain large fish. If any of you are going up to the Mall of America, I'd recommend eating (or take least taking a walk through) the Rainforest Cafe. BTW - I believe the person that maintains the tanks at the Rainforest Cafe is a member of TCMAS.
