So eels reall CAN get out of any hole...

Do not fear friends! The eels are fine! But I am in a bit of a predicament...
Long story short, I made the assumption that they couldn't get through the TEETH of my overflow. GUESS AGAIN! My girlfriend called me in the middle of class panicked that an eel was swimming in the sump. She was too afraid to grab it out so I had to come home. Any ideas on how to keep these guys out of the sump? Literally the only space they can get through is the teeth of the overflow. I will put some pics of the empty tank here so you all can get an idea of what it looks like!
The eels are currently happily amongst their rocks "peeking" out as they always do... just in case you all were wondering!
Below is the best pic I have. Of course it doesn;t show the teeth at all... I am sure most of you have seen a tank like this. The teeth go all the way to the top eurobracing.

 

I was thinking of something like that I just don't know how to attach it?

 

Hmm that's an idea. That also means this mod would be permanent though? Not sure how I can go about getting that area dry enough for long enough for the glue to set.

 

A fine idea! I have a ton of zip ties. Surprised I didn't think of this! I think I will give gutterguard a shot. Wonder how badly it will reduce my flow...

 

So I used the mesh. I sorta did it on the inside of the teeth at an angle like you said Phyllis. I tripled the mesh up. I am pretty sure the eels were getting through the teeth. One of them was in the overflow itself and the other was in the sump again when I got home from work. Right now there is no way I can imagine these things getting though. I can see how it might get dirty quick. There is little light getting into the overflow (I painted the lid dark blue) so hopefully there won't be too much crap growing on it. I guess I can make it part of my weekly maintenance to blow it off so long as the eels stay safe /DesktopModules/ActiveForums/themes/_default//emoticons/smile.gif

 

These suckers don't cease to amaze me. Even with the mesh one of them made it through. The kicker is that it came back into the display tank while I was fiddling with the ladder to be able to get at it. Unfortunatley I didn't see the prison break just saw they were both happily in their cave at one point. I need more ideas!!!
