Accidental cory spawning?

[Bubble]

So we added water to my tank two days ago. It has five or six mature cories in it.

I noticed that the largest cory was particularly round and had reddish markings on her belly and was worried that she was sick. Later I noticed one cory "riding" on the back of another, though I didn't see them actually mating. When I had a closer look I noticed some small white balls stuck to the side of the glass.
It all seems to fit the online descriptions, but I'm not 100% sure...
Are these eggs? Are they spawning?

Mine spawn after a water change. I think to them it’s like when it rains in nature and it gets them going.

If your stocking info on your profile is correct and you just have the Rasboras and Cories, then you definitely have Cory eggs!

 

[FishPlanet]

Yep. Cory eggs! Congrats!

Oops, just updated my profile. I don't think that the male betta would've layed any eggs though for obvious reasons.

At least the large round one wasn't bloated or sick...
I only saw five eggs on the glass but they were eaten while I went to get new batteries for my air pump... Would there be others hidden in my mass of untrimmed plants?
And does my large female need any extra care after spawning? I know it can be pretty tiring for some fish, and I think she might be the only female in the tank.

No male of any fish lays eggs.

Yes, that's why I said the reasons were obvious.

There should be much more than five eggs unless their spawning was interrupted somehow. It is possible there are some on broad leaves of plants, but they like glass most of the time. You can remove them using a razor blade or similar item and hatch them somewhere else. I've got the best results when I removed parents and other fish, and left the eggs alone in the original tank. The eggs are tough and may be ignored by small species of fish but the wigglers will be very vulnerable. Your Betta can probably destroy the eggs as well.
Giving rest to the female is a good thought but I am not sure if it is worth the stress of catching and putting in a new tank.

I see cory eggs almost every day but even more right after a water change. I don't do anything special for my females after spawning.There is no need since I keep them well fed all the time. If you aren't doing so be sure to feed yours shrimp pellets. My little guys and girls get shrimp pellets, Hikari mini sinking wafers for bottom feeders, occasional blood worms, Replashy grub pie and some of everything I feed all the other fish in the tank. I call them my little vacuum cleaners because they clean up any food that makes it to the bottom.

BTW: I have at least a dozen females and lots more males. Just guessing because they move to fast to count I am guessing I have more than 25 corys in my 55 gallon tank. One or two of the females lay some eggs almost ever day. They plaster them where ever they happen to be when they are ready to release them.

Watch your female closely while spawning. It is interesting how she holds the eggs in her bottom fins until she is ready to rub up against something to release them. I see them mostly on the glass but often on plant leaves, the heater or the uptake tubes on my HOB filters.

Thank you veggieshark! My tank is chaos at the moment thanks to some faster than expected growing plants, so there's no way I'm going to be able to find all the eggs. I think because of the plant induced chaos at least a few baby cories might make it.
I've found another single egg stuck to the glass, so I'm assuming that there's more in there.
My only other tank is colder and I'm worried she'll out compete my pygmy cories, so I'll probably keep her in the same tank.

Thanks mattgirl as well!
Silly question, but when you say shrimp pellets, do you mean pellets designed for feeding shrimp, or pellets that are designed for fish but that contain shrimp in them?
Side question, how many cories do you think would be comfortable in a 30 gallon? I've been thinking of increasing their shoal size but I don't want to overcrowd anyone...

It seems my favorite Omega One Shrimp Pellets are now called Catfish Pellets. Amazon.com : Omega One Sinking Shrimp Pellets, 8mm Pellets, 8.25 oz : Pet Food : Pet Supplies
They are food designed for fish. I read the ingredients on the Omega one shrimp pellets I have and the catfish pellets I see now and the ingredients are the same.

I am really not the one to ask because I feel the more the merrier I would have no problem having a dozen of them in a 30 gallon tank as long as it isn't a tall tank with a small footprint.

Interestingly, the ingredients do not explicitly list shrimp. Even though it is presented as fish food, this suggests the pellets are meant to feed shrimp primarily. Of course, you coud interpret shrimp as one of the sustainable Alaskan seafood products, but why call them shrimp pellets if the majority of the ingredients is not shrimp? Now the whole thing became circular. In practice, it doesn't matter, you can feed this to fish without hesitation but this sort of logic issue bugs me as well.

Maybe this was brought to their attention thus the name change I noticed the Wardley shrimp pellets main ingredient is shrimp meal but is still for mostly bottom feeders.
