over flows and fire eels

[Charney]

I have been wanting to get a fire eel for years now. The only thing that has been stopping me is the trend of skinny fish ending up on the other side of the overflow. I have rigid up some fool proof blockers in the past that have failed miserably. What do you guys do to keep them contained?

use a mesh of some kind to cover the gap should work but these fish live to exscape they come from wet lands in asia and are allways looking for a better place to hunt and breed
also try preventing it from getting to the over flow insteed of covering the over flow its self

Nylons work well.
