How to catch a large fish in a reef tank

[Delphinus]

Tom I'd love to see pictures of your ARM container trap too.

Do you use something to weigh it down?

I've used a pop bottle (with the top cut off) in the past with great results but right now I want to relocate my CBB into an aiptasia ridden tank and it's not working out so well. The problem is it's too light and floats around in the current. When I used it last time I would just hold it in my hand. But this time he remembers that "container being held by human" is something you don't want to swim into. Although my hawkfish is all too happy to swim in anyhow. Doh de doh de doh, yum yum mysis!!! Doh de doh de doh.
