rigid acrylic tubing - can't find it

[iwishtofish]

Anyone know where to buy acrylic tubes? I am looking for something around 4" in diameter. I want to build a fish trap asap (my flame angel just started picking my corals).

I tried a local hardware store (big chain, too), a pet store, a party store, and a crafts store. No luck!

I'd consider a 2-liter bottle, but I'm not keen on the label glue and it would also be a little big for my tank. Maybe an online vendor?
