hi my little cousin got some triops from argos 2yrs ago and after he bought them it was too cold for them to hatch so he left them in its original box, and just 4days ago he got them out and tried to hatch them, but we’ve done what it said on the box. and its been 4days and i still cant see no triops, an on the manual it says ” they hatch in one day” and now im wondering if we’ve left it too long and the eggs are dead.
so are they dead or do i have to wait even longer?
