The South Pacific Gallery features seahorses, pipefishes, and colorfully patterned reef fish.

In July 2018, the aquarium expanded with the addition of a large North American River Otter exhibit.

The exhibit is multilayered with an upper-level with land, hiding areas, and plenty of dirt and vegetation with view of the large pool.

The ABQ BioPark Aquarium currently runs a facility that focuses in the conservation of fishes found in the Rio Grande.

The project includes the Rio Grande silvery minnow breeding program and the Socorro isopod.

A recent bond was passed to help bring in a North American Otter exhibit towards the existing Pelican pond.
