Oops...the rest of the story.
Get some breeder baskets like these

Hang the basket in the tank or sump.
Catch the fry with a turkey baster. You may have to make the hole larger so they don't get crushed.
The male always spit them out in the tank around midnight. If I was lucky, it was on the weekend. You can check on them hourly and once you see them out of his mouth turn the pumps off and suck them up with the turkey baster.
I typically caught from 16-24 at each cycle. After the cycle, be kind to the male and separate him so he can eat and fatten up. It's best to have another male to take his place. I broke the cycle once and it took a while for them to start breeding again but I got out of the hobby shortly after that.
An alternative is to wait a couple days before he should release and catch him in a net and he may spit them out. I was never able to do this.
Also turn off the lights and use a flashlight shining down in a corner and they will accumulate in that corner.
Good luck!
