danfrith,
Ghost Pipefish of the genus (Solenostomus) currently do not fall under CITES protection. These incredible looking pipefish are highly sought after for their vivid patterns and appendages all over their body, allowing them to "blend in" with the surrounding structures or plants in their habitat of sheltered costal waters and estuaries.
Ghost Pipefish have a very poor track record in captivity. The main reason for this is that these fragile fish need food constantly throughout the day, and when collected, transported, and held before export, they are not fed properly, or even fed at all. This time frame from collection to export can be upwards of 10 days. Once these fish are imported to the US they are very weak, and normally perish in a few days.
In the many years I have been in the aquarium trade importing and selling marine livestock, I have never seen one of these fish last more than 4 weeks in captivity. Although there may be a handful of success stories with these fish on a long term basis, that is definitely not the norm. Until better handling methods are employed overseas it is my opinion that in the best interest of sustainability for this fragile genus of fish, to leave them in the ocean, and not create a demand here in the states for these fish.
Although these fish are incredibly beautiful, I would encourage you to consider some other species that fare better in the home aquarium.
