The Rasbora trilineata or Scissor Tail Rasbora is also called the Three Lined Rasbora in some places. The Scissor Tails have a forked tail (caudal fin) that has black and white markings on it that are similar to the dorsal fin on the pristella tetra. There is a horizontal black bar on the mid section that runs the length of the body. The forked tail gives them a unique swimming style that is the reason for the common name. Their tail makes an opening and closing scissor like motion while swimming. It is rather neat to watch.
If you're looking for a nice, easy going community fish for the top parts of your freshwater fish tank this Scissor Tail Rasbora may be for you. They will bring lots of activity to the top levels of your aquarium and should not bother any of their tank mates.
Feeding the Scissor Tail Rasbora should not pose a problem since they will take flakes, frozen and freeze dried foods. They especially like freeze dried bloodworms, but don't over do it. A little bit of the freeze dried bloodworms goes a long way and only give them this food as a treat every once in a while. A good quality flake fish food should serve as the main part of their diet.

Scissor Tail Rasbora Comments
I really like their swimming style and the activity that they bring to the top of my 55 gallon. They like to hang out under the surface and occasional dart to and fro across the top of the tank. They have been very peaceful but they will stick up for themselves against my Columbian tetras that sometimes try to swim through the middle of their peaceful school. This is a good fish.

Gets big and likes to be in schools making optimal care conditions difficult in the home aquarium.
Males turn cherry red and these make excellent fish for beginning freshwater aquarium fish tank keepers.
The Glofish were genetically modified with the purpose to detect environmental pollution. Scientists were able to inject a fluorescent protein gene (from marine organisms) into the zebra danio embryos to create the glofish.
