Overflow Cup Issue
My tank has two very small fish in it, and I have a sump w/ an overflow cup on it. Twice now my juvenile tomato clown has fallen into the overflow through the slits. I am uploading a picture to show how wide the slits in the overflow are.
I'm looking for some way to block this, but I don't want to put a sponge over it. I don't want anything on there that will filter junk out. I just want it to keep fish from falling in. Something like mosquito netting or whatever.
