I bought 4 ghost shrimp last night, and turns out that two are carrying eggs. They look like brown pellets at this point, so I assume they won't be released into the tank for a while. I would like to try to save them from my fish eating them up...anyone else ever have this happen? At what point should I remove the two shrimp from the tank and isolate them? Will I need to keep the parent shrimp in the tank with the new shrimp or can I put them back with my fish?
