copepode hybrid!!

[PacificBlueReef]

I have had my 55g tank up and running for about 2 months now just as a refugium for my critters. Now i have hundereds to thousands of copepods, and I have noticed a few that look almost identical to the rest but are green. Any ideas what these could be?

Thanks

Copepods with a stomach full of algae.

That could be a possiblity but since i have not feed the tank anything yet they all have had the same diet. (algae and detritus from the rocks)

I think more than likely its a different species. Is their any information published about these little critters?
