Australia, Queensland, Chuwar

Colleges Crossing Recreational Reserve, a popular picnic spot and fishing area, is located roughly halfway between the source and mouth of The Brisbane River. This place also holds an abundant aquatic life.

This biotope aquarium is based on some of the smaller fish living in the area. The setup is based on the riverbanks of this beautiful area, with tree’s, grasses and other plants growing close to the shallow water of the river.

I have chosen to recreate the silty banks of these waters, which I find to be a very interesting place for both species in my tank.

Aquarium decoration

The substrate is a mix of fine sand, more coarsed sand and pebles in various sizes. Along with a group of larger riverstones, driftwood, leaves and branches.

I have chosen to recreate the riverbank with decoration concrete and styrofoam. This is painted and decorated with dirt, stones and branches to imitate the banks of the river as much as possible.

Along with this I have chosen to recreate the nearby surroundings above water as well. I have various types of emerged plants, grass and stones to recreate this area. Along with this I have made a small stream of water flowing down into the tank. This is to imitate some of the small and nearby creeks flowing slowly into the river.

In the background I have a mix of aquatic plants imitating the dense underwater forrest from the habitat.
