Has any progress been made in figuring out how to keep riffle larvae alive? From what I've read here and elsewhere, it's not entirely clear whether it's an issue of chemistry/hardness or food. This is a basic but important question, and I think it's easily answered by running a few experiments using water drawn from a creek where they naturally occur. Is there anyone here that can help?
This is a bit of a condensed version of several articles and videos below. Just wondering if there may be any additional info that may be beneficial on this journey. I have two berried females, the first one which already hatched out a handful of zoes? (didn't find hundreds of babies... only what could maybe be counted on one hand... only fish are kuhli loaches) Grabbed them last night and transferred to saltwater, this morning the female is already berried again. (can't seem to find a molt, so a little surprised there...) Second should be hatching in about two weeks, and hopefully there will be more. ~5 weeks from berried to hatch Do not need to be fed while in freshwater (at least the first 3-4 days?) Transfer to saltwater within 8 days of hatching (no acclimation required) Zoes are attracted to light Salinity between 30 and 35 ppt (1.022 to 1.026 sg) Air stone with reduced flow Temperature 68° F to 84° F? Diet Diatoms? Phytoplankton Tetraselmis Dunalliela Salina Nannochloropsis Rotifers? (zooplankton) Isochrysis sp. Tahaitian? Liquizell Golden Pearls (5-50 Microns - larger may work) Spirulina Powder (mixed with water) Mosura Shrimpton Light on for 16-24 hrs a day Morph into adults around 3-6 weeks of age Acclimate morphed babies (post larvae form) to fresh water within a few days over a period of 3 days, changing 50% of saltwater to fresh once a day - 4th day, move to freshwater Side Note: Adults survive salinity up to 17-18 ppt (for hatching in brackish water) - Adults cannot survive full concentration of marine water, eggs will not hatch in saltwater Resources; https://gabhar.wordpress.com/2009/11/11/breeding-amano/ http://aquariuminfo.org/amanoshrimp.html http://caridina.japonica.online.fr/English/Elevage.htm http://www.caridinajaponica.de/zuchtbericht.htm (German) http://www.shrimpnow.com/content.php/129-Amano-Yamato-Shrimp-Breeding (English version of above article) http://www.shrimpnow.com/content.php/288-Caridina-Japonica-breeding Video;
