Well I don't have an over flow or sump. Come tax return time I plan on getting one. I keep reading on them and seeing if I could make one but the more I read the more confused I get.
I have an opening on the back of mine that is about an inch or so but my filter runs back there and I have seen him swimming around up there late at night. From what I've heard you should keep it very tight as they will jump out but hasn't happened to me yet.
Guess the trip to ND was too far for ya...told ya you could have mine but you would have to come and fish him out.
Good luck and any more questions let me know.
