well if its only a FOwlr you can try the black screen that gores on screen doors. 1 ply of that he wont get through. but it will dull your lights a little bit not much thou. I use the black screen when im adding new bulbs i add around 3 plys and leave them on for 3day at a time then take one off .....

but ya off topic again :redface: that will and should work.

well it been a few days now and it still alive and eating lol

Nice eels. :biggrin:

I have a 65 with 3 eels in it, I just have the standard 'all glass' lid (I think). It has the plastic pieces towards the back and I just cut a couple small notches for my powerhead cords. I have all but one cord running along the top of the tank and exiting above my overflow so I can have a bigger hole and don't have to worry about jumping eels.

Glad to hear the eel has survived!!
