I was just linked to this thread because of a regal angel I have. Great video... you do make it look easy, but I'm nervous about injuring the fish's insides. Did you find a good tube to use? I was thinking about some of the larger fluid line we have at work, used in chromatography equipment... similar to this, but larger ID...

How soft or hard is best? And how to you know how far down to go?
Also, this may sound crass, but would you recommend practicing on a large damsel or similar first?
