Electric Blue Jack Dempsey

The Electric Blue Jack Dempsey is one of the bluest tropical fish and it is definitely one of the most beautiful!

An adult Electric Blue Jack Dempsey displays a magnificent blue coloration. This dazzling freshwater fish is a naturally occurring variant of the Jack Dempsey.  The Electric Blue Jack Dempsey is a magnificent blue and wonderfully attractive show type fish. It will do well when provided with adequate space and compatible tankmates. Unlike its parentage, this variety is slightly smaller and has been found to be a less aggressive cichlid, sometimes almost shy. They will do well in semi-aggressive communities. They like a tank bottom of fine sand, plenty of hiding places among rocks and wood, and a cover of floating plants. They do burrow and will eat live plants.

Adult Black Ghost Knife Fish

One of the most stunning and unique looking fish, the Black Ghost Knife Fish is sure to create a conversation. The body and fins are a jet black color, the base of the tail fin is marked with two wide white vertical bands.

The aquarium for the Black Ghost Knife Fish should be large with a small grained substrate.The aquarium should be fairly densely planted with many floating plants. The floating plants will help the fish overcome its shyness as it is nocturnal and sensitive to bright lights. Driftwood is also recommended along with some sort of inert piping for the Black Ghost Knife Fish to hide in.

The water in the aquarium should be soft, and kept at a temperature of between seventy-five and eighty-two degrees. The pH should be neutral to acid. Feeding should be a mix of live tubifex brine shrimp and meaty frozen foods. The Black Ghost Knife Fish is sensitive to water pollutants, changes in water conditions, and medications. Although timid they are aggressive to their own kind but can be housed with other large peaceful fish such as Angelfish, Discus and Gouramis.

Juvenile Marine Blueface Angelfish

Referred to variously as the Blueface, Yellowface, or Yellowmask Angelfish, the adult and juvenile Blueface Angelfish differ markedly in coloration. As a juvenile, the body is covered with alternating vertical stripes of black, white, and sapphire blue. Upon growing to approximately five inches, the juvenile begins to morph into its adult coloration of pale yellow with bluish scales and a bright-yellow pectoral fin. It has a mottled-blue face with yellow mask that extends from eye to eye but not much beyond each eye. There is also an eyespot at the caudal end of the dorsal fin.
 
A minimum of a 100 gallon tank with numerous hiding places and large amounts of live rock for grazing will offer an excellent marine aquarium environment. Not a good reef dweller, the Blueface Angelfish is prone to nip at stony and soft corals (sessile invertebrates) and clam mantles. The Blueface Angelfish is best kept as the only angelfish, as it is prone to becoming territorial when it is the largest fish in the tank.

The frequently fed diet for the Blueface Angelfish should consist of Spirulina, marine algae, high-quality angelfish preparations, mysis or frozen shrimp, and other meaty items.
