All our Medusa aquariums are hand built in the UK to guarantee the highest quality finish. The aquarium is manufactured from extra durable Perspex acrylic and comes with a clear acrylic lid.

Filtration is hidden at the rear of the aquarium enclosed in a sump unit. Included with the Medusa Mini is the filtration (Bioballs, floss foam mesh) and powerful yet silent Eheim 300 powerhead. To control the flow output there is an easy access flow restrictor at the top of the aquarium.

    This aquarium is excellent. It looks great. The maintenance is easy and the jellyfish love it!
    The design is so simple and the unit incredibly well made – the Perspex really amplifies the effect of having these fascinating creatures in your home.
    The mini Medusa is an excellent choice for a beginner jellyfish enthusiast. The price is very reasonable for what you get and the quality.

    TrustPilot Review

    Don’t hesitate to buy
    We got our jellies earlier in the year and will not hesitate to buy some again when we are ready.
    Rory was brilliant, has a wealth of knowledge and was super helpful when our first tank unfortunately was damaged by the delivery company! He took the time to answer all our questions (completely new to marine world) and provided guidance on what needed to get started.
    The jellyfish come with a useful set of instructions and arrived as expected. They were pulsing a lot when we got them which was great to see also!
