Species
The red-backed paradise fish is generally indigenous to freshwater lakes and rivers in and around China and Asia. More specifically, the red-backed paradise fish is prominently found in the Cam Lo River (Giang drainage), in Central Vietnam[3]. The fish generally is palegic, meaning that it lives in the palegic water regions of deep fresh water lakes in China and Asia. The pelagic zone occupies 1,330 million km3 (320 million mi3) with a mean depth of 3.68 km (2.29 mi) and maximum depth of 11 km (6.8 mi). [4][5][6]
Habitat
The habitat of the Macropodus erythropterus is of calm waters. They usually reside in places where the water is not rough such as in streams. Also, the streams they were found in were typically near hills. They like to remain close to the shore. The red-backed paradise often hangs near plant life. They are usually found where there are overhanging shrubs and much vegetation. Macropodus erythropterus is a freshwater fish. The red-backed paradise fish is also not marine. [7]
Internal Anatomy
The Gills: Used for breathing under water it consist of small fragment attach to the bony gill arch located just below the eyes. The Blood: Like humans, fish blood contain red blood cells and white bloods cells. However; their red blood cells contain nuclei (a mass of nerve cells in which fibers form connections). These types of cells direct their growth, metabolism, reproductive functions, and also transmits their genic characters. The Brain: All sensory information is processed here such as the higher behaviors (processing of what to eat do or react). The brain also commands the respiratory system differencing when the fish is above or below water. [9]
