Reefscape Australia Aquariums were appointed by Henderson and Lodge Architects to assist with 2 large glass aquariums required for a school science department.

 

Reefscape Australia Aquariums designed 2 aquarium tanks, 1 to display fish found within the alkaline waters of Lake Malawi Africa, the second to display the fish found in the Amazon river of South America.

 

Lake Malawi is the home to a unique species of fish called African Cichlids. African Cichlids area unique species commonly called "mouth breeders".

 

The female fish will lay eggs on a vigorously defended patch of rock and they are then fertilised by the male. On hatching, or in some cases before, the male fish will gobble all of his fry into his mouth.

 

From their father's mouth fry will leave to feed and explore their new underwater world, returning to their father's mouth for protection on command. ln this manner the fry remain protected until big enough to fend for themselves. A level of parental care that is rare, even in more sophisticated species of animal.

 

The Amazon river tank was proposed to be a planted aquarium, displaying discus fish, as well as other colourful acidic water loving species.

 

The discus fish is also very intriguing in its parental care. The male and female will protect their "nest" vigorously until eggs hatch. During the gestation period the male will begin to produce a thick sticky mucus from his skin. On becoming free swimming the fry will flock to their fathers flanks and feed from the mucus, also receiving the protection of their parents.

 

Both aquariums were filtered by fresh water refugium systems. A refugium is a refuge for smaller organisms and plants to thrive away from the preditation of the display fish. These organisms including worms and shrimps actually digest much of the waste created by the fish and assist its processing into plant soil or mud.

 

Nutrients processed by these organisms within the deep sand bed are absorbed by plants grown within this area. The net result is clean water, filtered as nature intended and a thriving ecosystem.

 

These filters were designed to become study aids which would assist teachers highlight many parts of their students curriculums. The filters also illustrated the importance of preserving less spectacular wet land ecosystems found in nature and the important roles detritivors (bugs and little beasties) play in maintaining our water ways.

 

Reefscape Australia Aquariums built 2 glass aquariums for this project and installed them at the school on specially built steel support structures. The aquariums were a hit with parents and teachers alike.

 

Features of Note:

  • Fresh water refugium (natural style) based life support systems designed to illustrate to students the natural process found in waterways that facilitate clean running water.
