Dragonfaced pipes are a beautiful species but in my opinion should only be attempted by very experienced keepers.
Pipes are carnivores and need meaty foods. Some may accept frozen foods but you would need to be prepared to feed live foods for the life of the fish.
They are a very peaceful fish and should be kept in a very calm tank, set up specifically for their needs. They cannot be kept with any stinging coral, the same as any species of seahorse.
If you are going to attempt them, I would suggest you do some really indepth research on their specific needs and keeping requirements first. Of course we should always do this before we aquire any live creature.
