Joshua,

I could not see the pics in your link. Said I wasn't authorized unless I registered. I am on enough forums as it is.

There is a vast size difference between the sexes tho.

Joshua,

IMO given the fact that both the brevis are swimming near the grouping of shells and the one towards the back is smaller and more narrowed bodied, I would have to say it's male and female.

IMO, if it were two males or two females I don't believe they would both be near the shells.

Shellies are very persistant in defending the shells they have claimed as their own. Once they claim a shell, they defend it against all but their mate.

I was able to copy and paste the URL for the pic so I am making my determination from that!!
