Doryrhamphus excisus excisus - Bluestripe pipefish
Very small (about 2-3 inch), very fast and brilliant swimmers. Male bluestripe pipefish have small "hooks" near their mouth. DonĀ“t keep two male pipefish in the same tank - the are really aggressive against each other.
I'm selling one >.< Too aggressive to my current one.
