Likely Reef Tank Suitable
Likely Fish-Only Tank Suitable
These fishes belong in the Order Gasterosteiformes and Suborder Syngnathoidei as members of the Family Pegasidae (Sea Moths) consisting of 2 genera, and 5 species.
This family only consists of five species, and of those five only a few are worth mentioning as they are rarely ever seen in the trade, and besides they are extremely difficult to maintain in captivity. For in-depth information concerning these fishes, checkout Reef Fishes Volume 1 by Scott Michael (ISBN #1-890087-21-1).
