Breeding the Congrogadus, or Wolf Eel Blenny

Ok so I'm going to post a log of the beginning of my attempt at breeding my 2 wolf eels. Any advice that can be offered would be wonderful, but I'm going to post logs as progress is made. First I'll state my setups and all available equipment.

A 55 gallon aquarium with various fish and invertebrates. T5 High output lighting, about 50 pounds of live rock, and various coral. 2 filters and a protein skimmer as well as 2 power heads.

A 40 gallon aquarium setup exclusively for my 2 wolf eels. One green one about 7 inches long and one red one about 13 inches long. The female seemed very interested in eating the smaller one so I have a divider between them separating the tank, that's been working great for a while. I feed both of them frozen silversides.

About 3 days ago I noticed my red eel(female) had a huge bulge in it's stomach, which I assumed was food not being digested properly. I knew they bred around November to December but the day before that I had fed her 2 massive silversides, larger than I ever had :P. Today I looked in the tank, she had shrunken to her previous sexy waistline and was surrounding a small cluster of eggs that were about 2 inches in diameter. After jumping for joy for 10 minutes I took the eggs in a net and moved them to the male's side of the tank. He immediately tightly surrounded them in a coil and started rubbing his head into them while swimming around and pressing the ball. I assume he was fertilizing them and that he was moving the eggs around to get to them all. The eggs right now a light purple color with a tiny little dark purple speck in the center of each.

I have a breeder cage with a little fake grass and a tightly knit net for the walls. I currently have that on the females side. If I can I will enclose a picture of the male around the eggs. Apparently 10-14 days from now those eggs will hatch and the female will lay another clutch of eggs. This will occur about 4-6 times total to my understanding so far. Any advice would be wonderful because I want this to work. Even though I'm not holding my breath because I know this is hard, if anyone wants any of the babies (should I succeed) after they're old enough especially if you help me I would be happy to give them to you, provided you pay for shipping :P. I just want some good help and succeed at this. Maybe cut down on the population being snatched from the ocean.

I will post asap anytime anything new happens. After I finish the entire log and provided there's any success I'll collect all the data into one paper and maybe get it submitted as an article to help others attempting the same thing. Any good advice will receive credit.

Ok so right now the eggs have changed color to brown. I assume they were fertilized properly. It seems like a lot of them are dying though. The entire tank is turning a little milky. On the next attempt I'll put the eggs in a separate container for incubation.
 
OK so now the eggs have turned clear. There are maybe about 20-30 of them left. There are whitish specks in the middle of each egg that has been growing. I wish that I had something that I could zoom in and see, but it appears that each speck has been growing over the last few weeks. I'm pretty sure they are maturing.
So far not many of them have died ever since I liberated them from their cannibal father :P. I'm about to do another water change on the tank and I'll try and get some good solid pics of the eggs if I can and post them ASAP. I really hope someone is reading this post and it's not for nothing lol.
As a side note, for the last week my female eel(the red one) has started to get swollen up again. I assume she is about to lay more eggs any day now. She's been due for about 3 days now. Also she's been begging for pickles and ice cream so once needs only to put 2 and 2 together......
