How To Prevent Small Fish Being Sucked Up Into Juwel Filter?

    This morning, I counted my 9 neon tetras and I only found 8. I looked inside the filter, took the sponges out and nothing was there. I put the sponges back in and a dead neon tetra was floating in the filter. We were sad because he was smallest one and my sister's favourite and now I want to prevent any more fish from being sucked up in the filter and dying.
    This is the tank/filter I have:  
    How do I prevent small fish from being sucked up in this type of filter?
    Thank you.

    I heard you can use stockings. Just basically put your filter in them.

    You can often get a cylinder shaped sponge with a hole through the middle that goes over the bottom part (if it's the right type of filter I'm thinking of), but if your fish don't normally have any issue with the filter, it's likely it may have already been sick or weak (or maybe had already died) before getting sucked into the filter.

    If I was looking at the correct filter system provided in the link above, I have no idea how a neon got through those thin little slots.

    The neon that died was the smallest one, probably about 2cm
    The slots look quite large enough for a small fish to fit
