Tropical Fish Keeping - Aquarium fish care and resources

I just found out my Matae cories spawed. I saw them this moring. At least 4 from what I could see before I had to go to work. Sadly I didn't know last night. I did my tank cleaning last night including the gravel. I prefer not to know if I removed any my accident. I'd be devastated. They look like little pepper cories. I think they are about a month old since they are about 1/2-3/4". I knew I had a preganant female but I wasn't sure if she was laying the eggs or my nerite snails. I got eggs all over. Hopefully they are all cory eggs and I will get more. Cooler water temps and bloodworms does the trick again. I think the problem would be getting them to stop if I wanted them too. Eventually there will be too many and i can't I keep them all. I will take them to my lfs for a credit and a good home.
