Oh that's good - I expected she would lay eggs, from the behavour you explained. Now, we just have to hope that the male has been in the pot at some point to fertilise the eggs!
All you can do now is wait and watch. Try not to make it too obvious that you're staring into the nest and don't shine that torch in there any more - if the female feels her nest is being threatened she may abandon this batch (eat them). The best success is when they are left alone with no intrusions.
Try not to do much tank maintenance right now (e.g. no gravel vacs or moving stuff around etc).
The eggs should hatch pretty soon, in the next day or two but you probably won't see any fry for ages because they will be miniscule at first and will stay in the pot with the female for a few days.
If they survive the first 3-4 days, she is then likely to parade them around the tank. The male usually goes ahead of her and burrows a hole in the gravel. Then they will guide the fry along to the safespot.
You won't be able to feed the fry anything whilst they are in that pot, due to it's tiny hole - but they will eat their egg sacs to begin with anyway.
Once they are out of the pot, you can start feeding the fry.
Here's how I do it:
Buy liquifry 1 and 2 - first week use liquifry 1 (it's a white liquid that you squirt a drop or two above where the fry are. The droplets burst and cloud the water around the fry but this soon clears. This provides nutrients for them. If you don't have any liquifry you can put some normal flake food into a pot and grind into very fine powder. Mix a pinch of this with a bit of tank water and sloosh into the tank above the fry.
A week after using Liquifry 1, I switch to Liquifry 2 which is a fine yellow powder (a bit like grinding your own from flakes).
You may notice that the fry count diminishes day by day - and if this is the case you know that they are being eaten off gradually. If you are determined to rear some of the fry, you will need to remove a few by the end of week 1.
It's not an easy task as the parents will charge at you like crazy for trying to steal their babies. You might find it easier using a turkey baster/syringe to suck the fry up and squirt them gently into the fry tank. But be prepared for war - and the parents will get very stressed at this time, so once you have done it, turn off the tank light and don't go near the tank for a while till they have calmed down.
You can buy (for about £7) a hard, plastic fry/breeder cage which you can attach into your tank with suction caps. They usually have their own little air stone and spray bar to ensure the cage is getting enough aeration. This is what I used, with great success. Don't use a net trap because the parents will try to suck the babies through the net and kill them.
At some point, once the parents have fully matured and have really got the hang of producing/rearing fry, they will stop eating them all and then you won't have to worry about rescuing fry as they will allow some fry from each batch to survive and grow!
If you need any more advice or info just let me know.
