Any idea how keeping these in captivity went? ZTL lists no holders of this species at the moment, and pipefishes/seahorses generally don't have long lifespans.
@SeaOtterHQ there are a good number of seahorse and pipefish species that have been maintained long-term and even bred in captivity (especially seahorses), but I don't think ghost-pipefishes (Solenostomidae) are among them.
