Highly venomous

This species is highly venomous and this venom can, under certain circumstances, be fatal.

In case of poisoning, it is vital to have as much information as possible regarding the species/poison. Have telephone number for the poison hotline close to the aquarium.
Since people can have different reactions to poisons, take precautions necessary to ensure your safety and that of your surroundings.

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.

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

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

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. 

Best in a shoal

These fish thrive best in a large or small shoal.

Description

When young these fish are mostly black, but become brownish with white or yellow stripes.

Family description (Plotosidae)

There is only species (Plotosus lineatus) in the Eeltail catfish (Plotosidae) genus that lives on the coral reef.
Eeltail catfish are excellent at removing leftover food and dirt from the aquarium.

These fish have poisonous spines by the dorsal and pectoral fins, so care should be taken whith handling. Their poison can be dangerous for humans, especially if one is stung multiple times. 

They have a lovely appearance when young, but are less attractive as adults.
Unless kept in a group, they will remain hidden. 

Eeltail catfish can swallow both fish and invertebrates in one go.
