Beware of
Jumps out of open aquaria

This species is known to jump out of open aquaria.

Can be a threat to small fishes, crustaceans and other invertebrates

This species can be a threat for small fishes, crustaceans, worms, snails etc.

Searches through sand for food

This species searches through the sand for food, which can make the water cloudy and shakes up detritus.

In an aquarium their natural food source in the sand is quickly exhausted.

Keep in mind
Frequent feeding

This fish requires feeding several times a day, especially when newly added.

When the fish can find its natural food in the aquarium it requires less frequent feeding. 

Requires plenty of space for swimming.

This species revels in swimming and requires an aquarium with ample space.

Docile

This species is very shy and docile, so one should be careful when keeping it with more aggressive fish.

Descriptions and further reading
Family description (Mullidae)

Goatfish (Mullidae) have a very characteristic "beard" which they use when searching the sand for food. The aquarium should therefore have a large open area with both sand and coral gravel for example. 

These fish are not particularly well suited to aquaria as they often die after a few months due to malnutrition.
To succeed with these fish, one must feed them a varied diet 4-5 times a day, this in addition, to them finding their own food in the aquarium.

It can be difficult to fulfil their dietry needs, as they quickly consume the natural food in the tank and the amount of feeding places a large strain on the aquarium.
They require a large amount of food when young, but less when fully grown. 

Goatfish are considered predators, as they will eat small fish and crustaceans.
