Median Fins - Fins that are unpaired.
Metal Halide Lights - Very brilliant and broad-spectrum lights used in some Planted Tanks for growing plant species that demand high-intensity light to thrive, and in saltwater Reef Aquariums.
It had more numerous, smaller spots on the body, lines rather than spots on the median fins, and a white patch at the end of the tail. However, further investigation has shown that these color differences are a function of the individual's size.
The fish possesses two sets of paired fins (the pectoral and the pelvics), and two single ones the dorsal and the anal (also known as the median fins) plus the caudal fin.
Median fins have a thin iridescent blue coloration on their edges. The iris of the eye is bright blue or purple. Females tend to be paler than males, have a slightly rounded dorsal fin and a shorter anal fin (Sterba, 1983; Page and Burr, 1991).
Distinguished by the extremely elongate body, reduced cranial shield, confluent median fins, small eyes and presence of pelvic fins.
