Two weeks plus and I think I lost 3/4 of my hatchlings. I can see only a few today after coming home. I think it could be because I topped up some water yesterday... and I didn't aerate the salt properly to mix it. The number of shrimp i see today is very few compared to the swarming mass I started with. Bad bad call to top up water yesterday, they seem more sensitive to things like that now. Should've left them alone. I think a rough estimate would be about 15 shrimp, and I see some have grown very large, relatively speaking. One of them look like a mini-shrimp already. I dunno when i'm supposed to take them out for freshwater. Guide says they shhould go through metamorphosis first, start behaving like shrimp and scrounge at the bottom instead of just float around aimlessly. I think a lot of the shrimp was badly affected by the top-up yesterday. Probably because i'm such a newbie with adding water of the same salinity. They probably experienced some sort of osmotic shock. I dunno. Aiyah... I read many casualties happen during the change to freshwater.. with the numbers I have.. chances are i'm going to be left with 1 or 2.
