They just keep getting dunked under water every time they pass by the HOB filter flow. More and more keep dying because they’re always being spun around under water.
Do i have to choose between having a filter or having floating plants?

What would you guys do in this case to keep them alive?

Create a barrier with some plastic on the other end of the HOB filter, or if you could, make the flow lesser from the HOB.

What sort of barrier? I do feel that the HOB is too important for surface agitation and filtration for the fish. I will try and youtube how to make a barrier

You could cut a piece of 10 ppi foam that will fit across the outflow of your HOB.
