The Hawaiian Dascyllus or Dascyllus albisella is one of the many different salt water fish that is native only to the islands of Hawaii.

Adolfo's Catfish (Corydoras adolfoi)

The Adolfo's catfish or Corydoras adolfoi is a species of freshwater fish that often makes its way in the aquarium trade. This tropical catfish is not very large, only growing to lengths of about 2.2" (5.7cm). They are part of the Callichthyidae family, and first originated in South America, specifically Brazil.  They have a silver body with a black band near the base of the caudal fin and over the eye.

One of the reasons they are so popular in the aquarium trade is their ability to breed in captivity. Simply provide them with a plant or stone for them to attach their eggs to and wait. It only takes about 4 days after the eggs are laid for the fry to hatch. Like other species of Catfish, they are also good at keeping the bottom of the tank clean.  This fish are sometimes called Adolfo's Cory and require a 25 gallon tank with the following water conditions, 70-79F, 6.0-7.5ph.  They are a peaceful community fish that is considered to be very easy to take care of.  You can check out the Adolfo's Catfish in an aquarium in the video below.
