Shrimps keep dying
its been 4-5 days since i put the shrimps now in my 2-3 weeks cycled tank, i put 30 RCS, 20 rilis, and 10+ amanos (dunno why i also put amanos there), at first i have 2 casualty, mostly because of my mistake, but now, everyday i checked theres 1 and only 1 shrimp dead each day, but what i notice is, these shrimps that dead are all most likely young shrimp (slender body and all ), the berried one are just fine, i even see some little tiny shrimplets running arround
the last dead shrimp that i found is in a weird state, it seems "skinless" probably it just finish molting, is it possible that other RCS or probably amano attacked it while its in it weak state ?, while i'm not sure about my calcium, ph etc (not yet tested it) it seems the tank fine, since i already add boiled and peeled egg shells all over the back of the tank, i also give them high calcium diet sometimes, and theres molt skin all over the place (some of it i remove since its just unsightly)
anyone have any idea about this?
thank you in advance
