Fish stuck in filter again

[Moonweaver]

I have a small tank with 3 glo fish, they've been living happily for ~2 years, but recently the smallest one has been getting stuck in the filter, he used to be okay after we turning it off so he could leave, but now he can't swim. We're not sure what to do since tjeu need the filter... Help?

buy some sponge and wrap it around the filter intake

Or buy cheap knee high panty hose , ring them out with just water to clean. Then you can attach to filter intake with rubber bands.
I do this a lot with success!
