I certainly like the idea of a troupe of shrimp. They race around the tank bumping into each other and generally acting silly most of the time so they could be likened to a troupe of clowns.
A full grown one is at the most 15mm long and a lot of mine are under 3mm so I wouldn't like to have to try to shell them if I decided to make some Potted Shrimp.. Now if they were prawns that would be a different matter.
Add// I just did a Google and would you believe it!! a collection of shrimp is really a Troupe. You clever man Taf. I have to say though that my husband recons it should be a Platter of Shrimp .. but then he does enjoy his sea food.
