I noticed today that one of my fish had gotten it's tail sucked into the filter pipe
. Luckily I was able to free it and it's still alive. It's not doing good and it's tail is bent pretty bad, but for now it's still alive. I have several small fish that this could happen to. I was wondering how to go about covering up the filter pipe to stop this. I've heard of people putting a mesh material over it. Where would I go about finding this mesh material and how would I go about installing it? Or if any of you have different methods I'd love to hear it. I just need some help
!
