Come join Big Al on the Holiday Party Path! Through a round canyon, the colors of red and green line the path with the spirit of the holidays. With the path cleared of the pearly white snow beside it, Big Al is ready to take the walk towards the party. This theme is made with a lot of gravel and a very steep slope. This creates the illusion of a deeper tank than it really is. The method of making the front of the path wide and making it thinner as it approaches the top makes this tank with a 12 inch depth look slightly deeper than it is. This is best achieved with a sloped gravel bed. The front should have no more than an inch of gravel which slopes up. This particular gravel bed sloped up to 5 inches! This is difficult to achieve with sand but can be done if the mountain is created by burying something in the sand to help keep the shape. The path is also winding or is not straight front to back. This allows for the trail to look longer than it actually is. The placement of the rocks helps with this as the main left boulder creates the first deviation. The more rocks that deviate the line, the deeper the illusion makes. That being said, the more deviations will also require the gravel to be even higher.
The placement of these decorations allow for a large swimming space perfect for open swimmers like guppies, or schooling fish such as tetras and rasboras. The boulders also provide adequate cover for fish that are not so happy in open spaces. Due to the high gravel, it is important that regular gravel vacuuming is done to avoid excess waste build-up and possible anaerobic gas bubbles formed by bacteria.
