Haha, wow! And hour! I haven't back-tracked in a while, this thing is really getting long xD
Actually, I'm probably the last person you want to be asking about breeding advice.....My success is pretty much pure beginners luck
So, take my advice based on my experience with a grain of salt....
I didn't use the ice-cube method, I plan to in the future however. Though yes, you can use that for the first week I believe, though I used BBS from the beginning along with egg yoke. I wouldn't recommend this however for a first-time spawner, instead try and get some live plants and/or culture infusoria as food for the first few days then introduce Microworms/Vinegar eels/BBS. You can try the egg yoke as a first food, though be careful, your fry may not take to it.
I didn't change the water as much as a should have, though you should change it several times per week at the very least. Some say start after two weeks, some say after a few days.....I waited 2 weeks before the first water change, though I wish I would have started after a few days now.
Currently I change the water every day.
About 80 made it until I started have trouble with the ones I've jarred, currently its dwindled down to about 60-something, though I can't tell you exact numbers because I still can't count the ones in the tank ^^;
Hopefully I answered all your question....but, again, I advise that you do more research and not do what I did...I made a lot of mistakes
