My female lab has been holding for 4 weeks now and I was starting to get kind of worried about her. She's gotten really skinny, and her poor little mouth was just bulging with fry. I'm not too interested in breeding, so I decided to strip her so I could feed her up. Man was that scary. I don't have a separate tank, so I stripped the fry into a breeding net, so she would pick them back up again. I was so scared I would hurt her and I'm sure I stressed her out more than it scared me, but I did it. I got about 10 fry from her before she really started freaking out and wouldn't spit anymore. So I let her go, and wouldn't you know, she's still got at least two more in her mouth. I'm sure she hold them until adulthood just to spite me.
The fry are about 1/8", and they don't seem to have their egg sacks anymore. Well, gotta go to work, I'll see if I can get some pics when I get home.
