The Neon Blue Tux Guppy is also called the Millions Fish and sometimes, simply the Guppy. It is one of many color variations of Poecilia reticulata guppy. The hardiness of the Neon Blue Tux Guppy, as well as the fact that it matures quickly makes it an excellent fish for beginning hobbyists. The Neon Blue Tux male has a striking neon blue tail fin and neon blue coloring running along the top of his body. His underside from the anal fin back to the tail fin is a dark blue that turns into a mixture of colors at the front of the body.
The Neon Blue Tux Guppy requires a tank with at least 20 gallons of water, and is very tolerant of changing tank conditions. Plants should be hardy varieties such as Java Fern and Java Moss that can handle the increased hardness in the tank. Other peaceful fish would make good tank mates.
The females in this pair are of an assorted variety; however, you can differentiate the males and females easily. The males are smaller in size, have brighter coloration, along with a bigger tail fin, and pointed anal fin. The females are larger in size with a duller coloration, a rounded anal fin as well as a pregnancy patch on the lower portion of the body. Ideally, the environment should have a covering of floating ferns and a breeding box to protect the fry. Adults may eat the fry if left to fend for themselves without the breeding box. The fry should be fed brine shrimp, micro food, and pulverized flakes.
The Neon Blue Tux Guppy is an omnivore and requires both algae-based foods as well as meaty foods. An algae-based flake food, along with freeze-dried bloodworms, tubifex, and brine shrimp will provide guppies with the proper nutrition.
