Consuming this animal can trigger the dreaded Ciguatera fish poisoning.
The cause is to be found in certain unicellular organisms (dinoflagellates, such as Gambierdiscus toxicus), which produce toxins in the body of harmless and otherwise well-tolerated food fish, which can lead to various symptoms in humans:
Initial symptoms: Sweating, numbness and burning, especially around the mouth.
This is followed later by chills, dizziness, nausea, vomiting, diarrhoea, abdominal pain and muscle cramps. Paresthesia (itching, tingling, numbness) on the lips, the mucous membrane of the mouth and especially on the palms of the hands and soles of the feet, numbness in the hands, feet and face.
Paralysis of the skeletal muscles, including the respiratory muscles, dizziness and coordination disorders may occur. Muscle pain, joint pain, headache, toothache, shivering and sweating are further symptoms. A general feeling of weakness develops. Consumption of alcohol aggravates the symptoms.
Less common are life-threatening drops in blood pressure and palpitations (tachycardia) or the opposite. Overall, the condition is very rare, but it leads to death in about 7% of cases.
Attention: An antidote does not exist!
First aid:
As early as possible: Pump out the stomach, if vomiting does not occur by itself
Activated carbon (medical carbon) give to bind the toxins: dosage is 1 g / kg body weight.
Promote excretion: As an acute therapy, the attending physician can give an infusion of 20% mannitol (sugar alcohol). The mechanism of action is unclear. Mannitol promotes urine excretion, so this measure should only be taken after fluid and electrolytes have been supplemented to prevent a circulatory collapse.
Rehydration with fluid and electrolytes is a sensible measure anyway, especially after vomiting and diarrhoea.
In life-threatening situations, plasma expanders should be given, i.e. infusions that increase the volume of the blood and remain in the circulation for a long time.
Cardiovascular symptoms may require further medical intervention: Atropine can be given if the heartbeat slows down, dopamine if the blood pressure drops.

Due to the natural hunting instinct, shrimp or even small fish are considered food and, if the size is suitable, are also hunted and eaten.
Even cleaner shrimp can fall victim to the hunter if the hunger is correspondingly large.
Feeding
Because of the food requirements (whole dead fish or whole dead shrimp or other pieces of food) and / or imitation of a live animal and / or the dangerousness of the fish / crustacean (bite or puncture injuries to the keeper) should be
The bite of a moray eel can also be fatal for humans, depending on the size and bite depth of the animals.
The penetration of the pointed teeth of a moray eel into the human skin is very painful in any case and a doctor should definitely be consulted, as the saliva of morays is poisonous and contains a variety of different bacteria. In any case, a doctor should look at the bite marks to treat or rule out possible blood poisoning
Please always feed moray eels with feeding tongs to avoid accidents, no matter if the animal(s) is/are trustworthy!
Attention: The fish may bite divers in their fingers.

Jumping guard
A jumping guard prevents (nocturnal) fish from jumping out.
Wrasses, blennies, hawkfishs and gobies jump out of an unprotected tank in fright if their night rest is disturbed, unfortunately these jumpers are found dried up in the morning on carpets, glass edges or later behind the tank.

A small night light also helps, as it provides the fish with a means of orientation in the dark!
