Dwarf Crayfish eggs

Hey fish keepers! I wanted to know if anyone that has experience with crayfish eggs and care for to give me some info about them. So i have a 5 gallon freshwater planted tank with 3 orange mexican dwarf crayfish with some dragon stone to help them hide. They have been in there for about a 2-3 months and they seem pretty happy. Ive been feeding them hakari invertebrate pellets and they seem to like them and have been molting and showing signs that their healthy. Well recently I’ve been having an algae outbreak so ive been turning the lights off for most of the day with 2 hours of light so my plants dont die and its been going good...However i noticed one of my crayfish has like 30 eggs under its tail waving them around and was happy that im gonna have babies but i started doing research and this is where my questions come in. So i wanted to know if there is a way to tell the eggs are fertilized while on her? They are black at the moment with no transparency. And since i have dragon stone with a ton of little holes everywhere , do you think that its possible for most of them to hide and survive? And last but not least , what should i feed my babies so they dont die?
appreciate the help guys!!

 

I don't think crayfish eat their babies so they should be fine. You could always add so.e fake plants for them to hide in.
I reccomend a sponge filter or a sponge on your current filter intake so they dont get sucked up.
Feed them tiny foods that will sink, crushed spirulina has both plant and vegetable matter in it and might be a good choice it just takes a bit to sink.

Not only do they eat their babies they will fight to the death

Sorry I have a self cloning crayfish I didn't realize that other crayfish ate their young.

 

Yes mine have now point of interest we are not allowed your cray in the uk and i didn't know self cloning didn't eat their young so it seems theres no right or wrong answer here, thanks for the heads up on that one
