Hi Green Eyes,
Sorry not in the know about betts, but found this which might be of help:
Egg Bound No More!
by Stephanus Budidharma
Being egg bound is a condition where the female can't release her eggs. Some females became really large where the egg sack is located in the abdomen after attempting to spawn. Some people believe that spawning the females at an early age can reduce the chance of being egg bound. Recently, I have successfully released the eggs from an egg bound female. The female is still alive, swimming around and eating. Hopefully, in the future I will be able to successfully spawn her.
If you have an egg bound female, you can try this trick. However, you should remember that this is not a recommendation. It is for educational and informational purpose only. You are responsible for any loss if you decide to perform this to your fish. Your result might not be the same as mine. If you decided to do this, then you should get a towel to put the female in and a small container filled with water in which to drop the eggs. Take her out of the water. Gently put her on the towel.
