Sexing Yasha gobies and Harlequin Shrimp

[landonl]

I talked to someone at the meeting last night about how to do this, so thought I would post it here also, along with some links.

Yasha goby males have dark tips on their pectoral fins, where as females do not.
See this article for detail:

For Harlequin Shrimp, the females have marking patterns on the swimmerets under the abdomen, whereas males swimmerets are not colored.
Look about 3/4 of the way down this page for pictures.
