Yes, Ms. Inchworm does pamper her babies with blackworms. She has wonderful success, too. How many grow out tanks of how many cories do you have now?
As I understand it she just puts them all together in a tank, feeds tham blackworms, they get happy and make babies.

You can't argue with success. I feed almost exclusively blackworms now.
I don't know what is the right way, but I do blanch my peas in the microwave first, then I shell them. I give each betta about 1/4 of a blanched pea, mashed between my fingers. That makes it easier for them to get a bite, and I think they are also attracted by the odor. If they eat the 1/4 I give more. I don't have to fish out pieces of pea.
BN love cucumber. I can't remember now how my Betta did with cucumber, but I think, if they loved it like they love peas, I would get it for them. If you give any of your fish cucumber, blanch it too. It is easier for them to eat, I think. I always left the seeds. They seem to like the soft part. But I don't know about seeds. (This is other fish I'm speaking of.)
I would cut the cucumber into smaller sizes too. Again, it's easier to add to the tank than get out of the tank.
My BN (bushy/bristle nose plecs) died in a medication and culumnaris scourge recently, so I just give everyone a pea and some algae tab occacionally. The goldies get pea and orange (which makes a mess.)
