Our dedication to the health and happiness of our jellyfish is evident in our responsible breeding practices. We ensure they are given a habitat that allows them to flourish, reflecting our commitment to ethical and sustainable animal care. We do not catch jellies in the ocean, we breed all of them in our specialized breeding station.

The aesthetic appeal of our tanks is undeniable. Each is a testament to exceptional design, marrying functionality with style. The contemporary designs are meant to be timeless, fitting seamlessly into any room or decor style.

A Natural Stress Reliever

Birthday gift

Beautiful aquarium! Unfortunately, we didn't have the budget left for a bigger one, as it was a birthday present. We are now cycling the aquarium with bacteria and waiting for the delivery of the jellyfish.

Absolutely stunning!

Thanks again guys for everything. Love my jellies.

Nice colors!

We bought the kit for our office desk and constantly changing colors, depending on our mood. Jellies are reflecting light just perfect.

We´ve purchased this tank just 2 weeks ago, but everything seems good. Jellies are very happy and active, we are feeding them 3 times a week. Delivery was within 2 days. Thanks again. Michelle
