We always enjoy air museums and aquariums. We have been to several in several states. The one at Sea Center Texas in Lake Jackson is one of the most impressive we've seen and it was free..my kind of price.
The aquarium was complete with a 250 lb Grouper named Gordon. What a fish.
The Center is complete with a tour of the hatchery and an explanation of how the Center was begun in an attempt to save the Red Fish as a sport fish off the Texas coast. Lots of good information about not only that fish but the fishing industry in general.
Made we check the case when I bought shrimp later. I wanted to be sure they were farm raised rather than caught in the wild where other fish are destroyed as the shrimp as caught.
