We can't diagnose the problem without all the facts. What I can say is that fish will not get pulled into the filter unless either the filter is too strong or the fish is weakened by something.
A nitrate test kit is one of the basics you should have, along with a pH test. Ammonia and nitrite are advisable during the initial couple years, less necessary after that if you have a planted tank. But both pH and nitrates can tell you a lot about issues in the tank, as these can quite suddenly change.
If nitrates are high, it weakens fish, and this can be the start of other problems. And I asked about GH because neons are soft water fish, and the harder the water, the harder they will struggle just to "live" day to day. And this too weakens them. The GH you can ascertain from the municipal water supply folks, probably from their website.
