Jelly Fish Tank Round Black with Adaptor

No. It either phases slowly through a colour sequence or holds one fixed colour. That makes it the sensible choice for a room where the infinity mirror's flashing sequences would be a problem.

It is described as mains powered but the supplier does not specify the plug type and we have not sighted one. We have asked them. Whatever arrives, have it tested and tagged to your site's schedule before it goes into a classroom.

The supplier describes it as near-silent and quiet in operation, which is what allows it to run during reading or quiet work. They do not publish a decibel figure.

No, and the supplier says so explicitly - do not add real jellyfish or other animals. It is a sealed decorative tank with a motor, not an aquarium.

It turns itself off after four hours. In practice that means it cannot be left running all weekend because someone forgot it, which is worth more in a school than it sounds.
