You can be in and out of here in 1/2 hour, probably no more than 1 hr. It is a small aquarium but very nice. The attractions are very interesting. They have a lot of native fish to New Mexico which was cool to see. Their sting ray display was great! And the shark attraction was fantastic. But as I was standing by the exit door I heard person after person saying, "that is it???" Meaning, it is a very small aquarium but since it is part of the biopark and you can get a combo ticket to also enjoy the zoo and botanic gardens, it is a nice place to go with the kids that won't be too overwhelming. My son loved it!!
