Genus description (Platax)

Batfishes are not well suited to coral aquaria, as they pose a threat to shrimps, anemones, corals and other invertebrates.
They grow fairly quickly, a small fish can grow to be 25 cm in height within a couple of months. 

These fish will begin eating quickly, with the exception of Platax pinnatus, but will sometimes hide for a few days after being transported.
Be careful when catching the fish as their fins are easily damaged.

Batfishes should be fed with both algae based foods and different types of frozen food or seafood.

Family description (Ephippidae)

Many Spadefish cannot adjust to captivity and become much too big, but several species of the Batfish (Platax genus) can be kept in a large aquarium.
