It's funny this post came up. I have 4 and 6 inch pieces about the size you are looking for and there are fittings aswell. I was just about to throw out. I used to have eels and I was cleaning up over the weekend and put them in a box and I have been forgetting to put them out with the garbage. If you want them they are yours. LMK...
Are either of you going to the swap? I would like 1 4" and one 6" piece if you have them. There was a really cool aquascaping article in Marine Fish magazine that I want to try.
I am not going to the swap. I might be meeting up with NYreefNoob to get some fish on the day of the swap, maybe I could give to him and he can bring to the swap.
