Sorry I don't have photos of the brood stock. I got the larvae from a retail store 2 1/2hrs away. I can email him to see if he will send me a few pics of them.

It'll be important to know which form of Harlequin shrimp you have, I noted you named them as H. picta...seeing that among all the H. elegans reports, it clicked that there might be more than one type of Harlequin shrimp. A cursory look on my end revealed that H. elegans may be the accepted name, with H. picta being treated at times synonymous but by others as representative of a different population with different coloration. I learned something new today because of this post...I'd love to see more!

From my literature search I found that elegans and picta have been used synonymous. Some references suggest that the differences between the two are based on color differences. I also found a reference that stated picta is more common in the trade due to location of elegans and collection of the shrimp for the aquarium trade (I will look back and post my references). I have various color forms from blue to the rusty brown spots in both clutches I have been able to raise. 22 shrimp from the first batch and currently 30 shrimp from the recent batch. Truthfully I am not sure which species I have, I just went by default of which one is more common in the trade. Sorry for the confusion.

I found my reference in a pdf Fiedler 1994 Larval Stages Harlequin Shrimp. It says there are two color forms of picta. The red/maroon from the Hawaiian Islands and blue brown from the Western Indo-Pacific and Red Sea. The paper also states that shrimp from the Eastern Pacific (Panama and Costa Rica) two color forms are separate species blue being elegans and red being picta. There is no morphological basis for the separation , except color.

Hi Dave, I don't have the mating pair of the shrimp I raised. I was contacted by a retailer that has the pair in a tank by themselves. The tank is approx. 76 liters with a basic hang on filter and protein skimmer. I was told he feeds the pair a chocolate chip starfish (Protoreaster nodosus) approx. once a week. A kreisel would be an ideal tank for raising the larvae but I don't have one on hand. I used black round tanks instead with a 1/2" bulk head at the center bottom of the tank. The bulkhead has a mesh 75mic. screen with an air ring around it. The idea behind the air ring is to create a circular upward current to help keep the larvae suspended and keep the larvae from being sucked onto the screen. I'll post a few pics soon.
