Rob,
Sorry I missed the part about size. Around 6"- 8".

I have something in mind...I am out tonight, but I will see what I can do over the weekend. I could not find a suitable coloured material last night so may have to order in. If I remember, they are a mottled brown on the top with a dirty cream belly? Big whiskers too
The flies in the picture are about 6", but lengthening the tail would be easy enough.
I used to keep some in a half barrel along with a lung fish and some climbing perch and when we left Brunei my dad said, "You will have to take them back to the river". I just tipper the barrel over and they "walked" the 10 yards back to the sungai! Amazing creatures!
