Soapfish - Grammistinae
SOAPFISH - GRAMMISTINAE There are around twenty four different soapfish amongst this grouper subfamily (Serranidae). Their name comes from the bitter tasting slime layer (grammistine) that they have over their body and this helps to keep predators at a distance. Poison is only released when they are stressed and it also helps to protect them from parasites. Soapfish are known to be able to kill all the fish in a aquarium in a few minutes. A few species live below thirty meters and are active at night. This is one of the reasons why not much is known about this family. Length: 25 cm. Distribution: from India and Maldives to SW- Japan, P.N.G, Vanuatu and Australia. Bright or pale yellow body and fins, wide blackish bar central body and black eye bar. Occasionally completely black with yellow fins. Always close to caves and crevices where they can hide. Lives solitary or in small groups on coastal rock or coral reefs, from -1 to -18 m. Length: 15 cm. Distribution: from India towards SW- Japan and Australia. An only member of it’s genus. The scorpionfish look will help to discourage predators.
