| Aeoliscus and
Centriscus Shrimpfishes are related to sea-horses and like
them are characterised by a strong exosketeton of horny material. A much more striking
feature is the curious habit of swimming permanently upside down. Furthermore, the
extraordinary mobility and incessant activity of the expressive eyes, coupled with the
permanently head-down swimming position, makes the fishes look as if they are forever
searching for some treasured possession recently lost. Again it must be said that unless a
well-matured natural system tank and thousands of brine shrimp nauplii are available
daily, these enchanting creatures should never be removed from their reef homes.
