Question And egg in the cooker?

Dumb question: how do you know if a danio is going to lay eggs (or do whatever it is they do to reproduce)? My largest female danio looks like she ate a rock and she's been chasing all the other danios away from the top of the tank. She's certainly not in any distress and other than not wanting the others close to her, she's acting normal. Am I about to have a disaster?

Oh, and more information that might help: I have three male and three female danios and a betta named Renoir (my CAE died suddenly two months ago) and the tank is not planted. I used to have seven danios but the smallest one started acting sick and Renoir ate him, so I know Renoir has no qualms about eating slower fish so having eggs or fry in the tank would be a real treat for the betta, but a disaster for me.

I haven't seen any spawning behavior, but that doesn't mean there wasn't any to see. I was on vacation for 6 weeks and the guy who was taking care of the fish didn't spend much time watching them (weird, I know), so he wouldn't know either. When I came home she looked like that.

There are two other females and one is starting to look round as well, the other is certainly bigger than the males but not as round as the other two. I don't even know what to look for as far as eggs go. Am I dumb or what? What do I look for? The only eggs I know of are from the snail and Renoir eats any of those he can reach.

maybe our danios aren't pregnant at all. if they were.the males would be chasing them around and nipping at them.live bearers tend to do that a lot. i was looking for signs of pregnancy in my danios this few days.saw a pregnant ghosts shrimp but no signs in the danios.

My males are way too scared of that biggest female to nip, she's always been the Queen and no one messes with her, even Renoir leaves her alone. However, I do see a possible (yet icky) way out. I looked it up and danios scatter their eggs over the substrate the eggs are non-adhesive and tend to get eaten unless they are protected by marbles. I don't have any marbles and Renoir has a taste for caviar. Problem solved. I think if your danios are going to lay eggs, your ghost shrimp will probably eat the eggs first chance they get (I had one that would eat literally anything he could get in his mandibles, then he made the mistake of taking on a giant goldfish and I ended up picking him out of the filter in bits).

=S too fearless for his own good poor guy. i have java moss in the tank. it's used as a rcs nursery =) i do have baby shrimp in the tank so i'm thinking my java moss has done it's job fairly well protecting the little buggers so far. hopefully my danios will learn from them. amazing right i got predators in there and the baby shrimps are still alive

I'd love to feel sorry for that ghost shrimp, but I had a dalmatian molly who was feeling under the weather and he managed to sneak up on her and that was the end for her (I was not happy at all with him for that!) so I think of the results of him going after my goldfish as poetic justice. I really better get some of that moss when I get a bigger tank.
