I hope I write this post in understandable english. I can better reading than writing...
Let's go! My adults amano had and have everytime eggs. So I couldn't omit to try breeding amano. In the past I attempted this a few times, but
without success. The larvae died always at the latest after two weeks.
By the last experiment, the larvae hatched very late, considerably more than 35 days and after a water change. Directly after hatched, I transferred the larvae into saltwater with 20 ppt. I experimented earlier with salinity, between 19 and 30 ppt. So I think, the salinity isn't very important, but must not less than 20 ppt. The tank have 60 liters and a airpump. No filter, heater, substrate or decoration!
After 3 days, I feed them with little liquizell, every 2 days. When they are 2 weeks old, they were twice as large. After 25 days, I saw the first juvenile shrimps. Now, I feed them additional small pieces of flackes (Tetra Min).
At day 27, I changed the water (35%) for the first time. There were no loss as yet. After 34 days, there are less than 20 dead larvae. I think it's because feed has badly done the water. So I changed the water and decreased feeding.
After 42 days, I transfered the shrimps back to freshwater. I counted them... and there are exactly 323!
Im a little confused: I didn't nothing else than the other experiments...
Wow, I learned new english words. And you have opportunity to laugh
They are in freshwater since 10 days and have a bigness of ca 10mm. My next experiment follows in less than one months, 4 females has eggs
