The built-in LED lights are multi-coloured, giving you random red, blue and green effects within the display to provide hours of enjoyment. To maintain good water quality, don’t forget to add a small squirt of washing up liquid.

How is this jellyfish powered?
This magic jellyfish is powered from a mains power supply which is included, giving you everything you need to get your mini aquarium up and running.

Rated 4 out of 5 by from Mesmerising My brother bought this for my sons 1st birthday and we all love it. My son loves watching the jellyfish floating round and the changing colours. I like the feature that it turns off after 4 hours because it's in my sons room and wouldn't want in on all night. The only problem I found with it is one of the jellyfish didn't move round but after a few pokes they're all floating round now. Also the stopper at the top is really hard to get back on but a prod with the end of a wooden spoon sorted this (if it wasn't for this I would have given it 5 stars) Excellent product, we might even buy another one for our living room. Also other guests who saw it at the party now want one!

Rated 5 out of 5 by from I think this should be called the "Distractatron", I simply can't keep my eyes off it. Great though as the wife forces me to watch TOWIE... this is far more entertaining and believable!

Rated 1 out of 5 by from Awful quality control on this product, first one I had to return because the pump wasn't working so the jellyfish didn't move, so after a 40 mile trip I get home and the replacement doesn't work at all no lights or pump. Don't normally have a problem with maplin products but this is one is of low quality.

Rated 1 out of 5 by from Inferior electrics I bought this on friday at 5.30, set it up exactly as per instructions and yes it worked brilliantly for 3 hours and i liked it really good. It then turned itself off, and would not restart, a lot of money for 3hours :-(

Rated 4 out of 5 by from If it does not work, press the button harder and longer The concept of this product is very attractive but there are a few issues with the design and production. The instruction says you turn the back switch to ON and then press the front button and here it goes. However, as I have found out, to operate it, you may need to press the front button very hard or press-and-hold for a few seconds. I returned the first one I bought because it didn't start after I pressed the button (I tried a few times and even checked the mains adapter to make sure it's not faulty). The second one was just the same so in the belief that it is unlikely to have two faulty items in succession I tried to push the button a bit harder/longer and suddently it was on. I am not sure it is designed to respond to press-and-hold or it is just that the contact of that push switch is not very good on some samples, The plastic cap fits well in the first one but not in the second one. The moter is a bit too noisy (even noisier than my small fish tank pump). I agree with some other reviews that it would be really nice to timer/sleep function

Rated 5 out of 5 by from Worked great first time The plastic top is VERY hard to press in - best thing is to use a file around the edges bit by bit until you get a nice fit - I persevered as it looked great in the shop. They worked well for me 1st time. The kids love it. Water does turn a little cloudy after about 5 days and does need changing but that's been on ALL the time constantly - not a problem as the instruction do say to change now and again. Great product

Bought this today. Set up as per instructions. It lights up jelly fish but no movement & no noise from tank ???

Asked by: Charlie1959
Regrettably this does sound like a potential fault, and as such I would suggest contacting our Customer Service Team who can advise on the options available to you if the item remains within our standard 12 month warranty period. If your item is now outside the warranty period please do still contact the Customer Service Team as they may have alternative options available to you. Please contact customer care by telephone on 0333 400 9500 – Option 2, or email It will help to speed up the returns process if you have your receipt details / proof of purchase and postal address available at the time of contact.
