I think my Cory Breeding tank is 33 litres, that's about your 10 gal. So that's plenty of space. I have a decent sized Dwarf Amazon Sword, and that's a favourite laying site. Otherwise it's the glass, or annoyingly, the bottom of my Floating Fry Enclosure! I have pics of my setup and Fry over at

Collecting eggs is not always necessary, Cory's don't 'hunt' food like some other fish. However, it won't stop them accidently sucking up a wriggler whilst they're sniffing for food. But by collecting, you can control the feeding better, thereby improving the quantity and quality of your fry.
I have a little piece of clear perspex, that I often use to scrape eggs off the glass. And sometimes I need to cut the Pump, so that the current doesn't sweep them away whilst I do this. For the plants, I just snip off the leaf, and drop that straight in the Hatching Enclosure. If you don't chew your fingernails, then that's another good egg collecting tool.
The eggs are pretty tough, so it's hard to damage them. Although I feel, it may increase the possibility of damage, the longer you leave them, as they develope. So gather them in the first day. Getting them off your fingers can be a bugger tho', they're so sticky!
You can get different gauges of netting. I do get some leakage (I know, because my other fish hang around the down-stream end). You can wet the food first, to ensure it sinks to where the fry can reach it. My Airstones ensure dry powdered food leaves the surface fairly quickly.
I wish you all the best. Nothing beats your first batch of Cory's!
