You don't say what filter you have, but I have an Aquaclear filter
with a conical dip tube intake with rather wide intake slots. To keep
large chunks & snails out, I've cut a hole in a small Aquaclear sponge
filter and put it over the intake tube. This keeps live things from
being sucked into the tube. (Previously the filter was sucking snails
out of their shells, but now my shrimp can land and take off from the
sponge with no problems.)

I've got the same Aquaclear filter setup here also. I'd begun
speculating about how I could modify a little piece of one of my wife's
nylons in order to prevent this from happening again, but your approach
is much better- thanks.

This little cat is now against the glass on his side at the bottom.
He's almost certainly not going to make it, but I'm not going to
intervene *again.* I'll make sure this never happens again, though.

Regards,
Ian.
