Neon Tetra Nearly Sucked In By Filter

    I am currently cycling a 240l tank with 8 neon tetras (this tank + filter:  )
    Just now, my sister told me a fish was being sucked in by the filter and couldn't move. So I closed the filter and the fish swam away.
    I feel uncomfortable with filter because before, it sucked in one of my 9 neon tetras and killed it and I don't want it to happen again.
    What can I do to block up this type of filter?
    (I think its holes are big enough to suck the fish into it)
    Please help ASAP.
    Thank you.

    Wrap a layer of sponge filter around the intake. Easiest way to do it. I use a coarse mesh but I have bigger fish.

    I had to replay the video a couple of times to see exactly where the intake was. It is on the back of the tank correct? Or is it the small slots at the bottom left of the filter?

    Slots on bottom left and top right

    Okay, two inlets. If you can cover them with sponge, that would be the best fix. That is a beautiful tank.

    The other thing that I did for one of my small internal filters was i rubberbanded a sacrificed net (those green fish ones) over the entire bottom half of the filter.

    Nighthawk, you would have to see this filter. The suction strength is the problem here. The net would not change the suction strength. Sponge over the slots would disperse the suction over a broader area and the neons would not get stuck to it. (Although I might use that net application in the future in my tanks)

    Ah ha. Now I see it. My apologies :)
