They'll hatch in 3-5 days. Most rams will be bad parents on the first go. They'll likely end up eating the eggs but on the second spawn they should get quite a few free swimmers. Rams will guard and care for their young so you don't need to separate the eggs. What you should worry about is food. Baby brine shrimp should do. If you get a second tank soon you might have it cycled by the time the second spawn has occurred. Don't be fooled though there is a slight chance you will have some hatch but not many.
Mmmkay have you ever kept/bred rams, or are you just repeating what you've read?
You should see wigglers in about 3 days.
They are terrible at parenting. I've never dealt with Bolivians, but have watched many GBR variants fail miserably time and again.
BBS are way too big for the fry to eat, they are tiny, so that is a waste of time for at least the first week or so.
About the eggs hatching, if the male is fertile and figured out how to fertilize them then they will hatch, if they aren't eaten. In most cases I've seen, either the male does a great job or a terrible job at the fertilizing part.
So if this is their first cluster of eggs, it's almost a given that I should expect a second round soon? The only LFS close to me are Petco and Petsmart. I think they wouldn't sell live baby brine, but how about frozen? This is probably a dumb question but will crushed up flakes work if I see freeswimmers? If not, I suppose I can take a trip to the one specialty aquarium store which is about a 20 mile drive. Last question, will the Cardinal Tetra or Zebra Danios pose a threat to the eggs or fry?
Think smaller. I raised my ram fry on greenwater and vinegar eels. Even the vinegar eels seemed a bit big, but were always added for good measure. I believe the greenwater/infusoria is what sustains them for the first several days.
Everything poses a threat to the eggs and fry. Once freeswimming, assuming the parents let them get that far and you manage to keep them fed, the parents will have a hard time keeping them all together, and any stragglers will quickly get slurped up by the other fish in the tank.
The only way I've ever been able to keep eggs/fry alive is by transferring them into their own tank which has been filled with tank water from the parent tank and inoculated with greenwater and filled with dense moss.
Best of luck.
