Troubleshooting for possible complications with the jellyfish

An air bubble has formed under a jellyfish

Normally the air bubble removes itself because of the movement of the jellyfish. If this doesn’t happen after a while you can remove the bubble by yourself with your hand. Take the jellyfish carefully and turn it around (with the back to the bottom). Now you can squirt water with the pipette under the jellyfish and the air bubbles will start to remove slowly. Take care that the pipette does not touch the jellyfish.

The jellyfish only move very slowly

It sometimes happens that the jellyfish swim slower than usual. This normally happens after you fed the jellyfish or after you’ve inserted then for the first time into the tank. Should this not be the case it is a sign for bad water quality. Exchange the water and remove the dirt and deposits from the tank. Also assure that the salt content is at 30-35g/L and that the water temperature is between 15-25C°

The jellyfish shrink and contract

This is also a sign for bad water quality. Divide the daily feeding dose in 2 daily portions. One in the morning and one in the evening. Exchange 50% of the water. Remove all the deposits and pollution from the tank. For this you can use the feeding pipette, the tank hose and the algae magnet. Also assure that the jellyfish get their food directly (pipette). Extra advice: additional water exchanges improve the water quality and the health of the jellyfish. It is also important to remove food remains regular.

The water is foul

Because of too much food in the water it emerges a bacteria growth. This is what makes the water foul. Decrease the amount of food and assure that your tanks is as clean as possible. Additionally exchange 25% of the water in order to decrease the water cloudiness.

A jellyfish is stucked to the wall or floor

Should the jellyfish for any reason stuck to the wall or the floor you should release it carefully with your hand or pipette. If the jellyfish has been hurt while removing it it is helpful to do a 25% water exchange which helps the jellyfish to regenerate itself.

A jellyfish is swimming on the floor

This is a sign for too low salt content. Assure that the salt content is between 30-35g/L. Adapt the water appropriate in order to get the needed amount of salt. After this it can take several hours for the jellyfish to regenerate and start swimming normal again. If you just inserted the jellyfish into your tank it can take up to 24 hours until they start swimming normal.

A jellyfish has a hole or fissure

A jellyfish loses its natural netting due to bad water quality. Do more regular water exchanges and assure that the water has as little as possible dirt and pollution. To much dirt harms the netting of the jellyfish. Now divide the daily feeding dose in 2 daily portions. Feeding the jellyfish more often and in smaller amounts decreases the dirt in the tank and increases the portion of food the jellyfish is actually eating. Extra advice: a big water exchange can improve the water quality significantly.

Foam is generating on the water surface

This is normal and can happen sometimes. But it will disappear after a while. The foam forms of organic molecules which stuck to the water surface and produce foam. If this happens you can simply remove the foam with a spoon.

The jellyfish moves in its tentacles

This is a normal reaction after feeding them. It helps the jellyfish to eat the food.

A jellyfish has turned inwards

This is also a reason of bad water quality caused by jellyfish scrap or uneaten food because of too high feeding doses. Exchange 50% of the water as soon as possible. Additionally free the tank of all deposit

and pollution. For this you can use the feeding pipette, the tank hose or the algae magnet. If the jellyfish didn’t regenerate or start moving after 48 hours we recommend to remove the jellyfish out of the tank in order to avoid more contamination of the water.

Algae is growing in the tank

Algae don’t harm the jellyfish but they definitely don’t look good in a tank. Use your hand, a sponge or an algae magnet in order to remove the algae inside your tank. If algae continue to grow uncontrolled we recommend to remove the tank from too much sunlight.

Salt content is increasing

The salt content increases because of evaporation of the water. In order to prevent your tank to be out of the recommended content of salt you have to check the amount of water inside your tank. You should always have the same water content. This could mean that you should add more often water to your tank in order to avoid more evaporation.
