Descriptions and further reading
Family description (Monodactylidae)

Moonfish (Monodactylidae) are unique, with their special shape and that they have a reflective skin. They are seldom kept in private aquaria, but seen occasionally.

They normally live in brackish water, but can get used to water with a salinity of around 35 (specific gravity 1.026). Larger individuals do better in salt water. Adult fish don´t thrive when moved from their environment, this must be taken into account when these fish are acquired

It is important to mimic their natural environment with proper hiding places, plenty of macroalgae and tree roots.

Because they have the the tendency to swim directly into the glass when frightened, this must be avoided. i.e. dim the light gradually and permanently have a nightlight on.
