This is the moment aquarium biologist Amanda Felix gave a goliath grouper fish a sand scrub while doing a maintenance dive in the 135,000-gallon shark and gamefish tank.
The goliath grouper (Epinephelus ) that was resting on the bottom had not ever been given a name by the staff at the Mote Marine Laboratory And Aquarium in Sarasota, Florida.
But when biologist Amanda Felix spotted the huge fish taking it easy, she decided to give it a ‘sand bath’, which the fish seemed to enjoy in this footage shot on the February 10.
Goliath groupers are large saltwater fish of the grouper family usually found in shallow tropical waters amidst coral and artificial reefs at depths from 5 to 50 m.
They can reach extraordinarily large sizes, up to lengths of 2.5 m (8.2 ft) and can weigh as much as 360 kg (790 lb), with the world record for a hook-and-line-capture being 308.44 kg (680.0 lb).
The species population began to rapidly decline especially in recent years due to their highly sought-after value for fishermen.
They are also relatively easy prey to spear as like this one they tend not to flee from man and reproduce in large aggregations making them easy targets.
