Fish getting stuck to opening on skimmer

[lookatmyfeesh]

I've had a couple fish get sucked onto the opening of my HOB skimmer and had to pull them off of it, i put a tiny square of mesh over it to prevent it from happening again, will that be ok and not affect the quality of how the skimmer works?

Looks like this model has a sponge on the intake.
