Ideal for children’s bedrooms the 15 litre baby biOrb Moonlight aquarium is fitted with a light which senses when the room is dark an automatically changes to a calming blue light. Baby Moonlight has all the same features of the standard baby biOrb. As the light cleverly senses when the room is dark there is no need to switch it on and off, however, this feature can be overridden so that it can be used as a normal light.
